Price shall be payable at the Closing as described in Section 3.2 below and shall be subject to adjustment as provided in Sections 2.6 (such adjusted Initial Purchase Price being the “Final Purchase
Price”). 
 f. Purchase Price Adjustment. 

 

	i.	 At least five (5) Business Days prior to the Closing Date, the Sellers shall deliver to the Purchasers a certificate (the “Initial
Closing Date Certificate”), certified and executed by the President of each of the Sellers, setting forth Sellers’ good faith estimates of (i) the Closing Indebtedness and (ii) the Sellers’ good faith estimate of
Working Capital as of the Closing Date 



  
 13 










	 	
(the “Estimated Working Capital”), along with a copy of each Seller’s good faith estimated unaudited consolidated balance sheet as of the Closing Date (the
“Closing Date Balance Sheet”) upon which such calculations are based. The computation of (A) Estimated Working Capital set forth in the Initial Closing Date Certificate and the Closing Date Balance Sheet shall be
prepared in accordance with GAAP on a basis consistent with Annex I hereto. 

  

	ii.	If within two (2) Business Days following receipt of the Initial Closing Date Certificate, (i) the Purchasers have not given the Sellers’ notice of its
objection to the Estimated Working Capital calculation or the Closing Date Balance Sheet, the Initial Purchase Price shall be increased or decreased, as applicable, on a dollar-for-dollar basis by an amount equal to the Estimated Working Capital
Adjustment as determined by the Sellers. If the Purchasers give any such notice of objection, the Sellers and the Purchasers will work together diligently and in good faith to resolve the issues in dispute. If all disputed issues are resolved, the
Estimated Working Capital as agreed upon by the Purchasers and the Sellers shall be used to complete the Estimated Working Capital Adjustment. 

  

	iii.	Not later than sixty (60) calendar days after the Closing Date, the Purchasers shall cause to be delivered to the Sellers a statement (the “Closing Date
Statement”) setting forth the Purchasers’ calculation of the Final Purchase Price (including the Purchasers’ calculation of the components thereof contained in Section 2.5 as of the Closing Date) together with
(A) the balance sheet of the Sellers prepared as of the Closing Date (but prior to the consummation of the transactions contemplated by this Agreement) from which such Closing Date Statement was derived (the “Final Closing Date
Balance Sheet”). The calculation of Working Capital set forth in the Closing Date Statement shall be determined in accordance with GAAP on a basis consistent with Annex I. 


 

	iv.	The Purchasers shall permit the Sellers and their representatives reasonable and timely access to the books and records, accountant’s work papers, personnel, and
facilities of the Purchasers to the extent reasonably necessary to review the Closing Date Statement, the calculation of the Final Purchase Price and the Final Closing Date Balance Sheet and for the purpose of resolving any disputes with respect
thereto. 

  

	v.	 Within fifteen (15) calendar days after their receipt of the Closing Date Statement and Final Closing Date Balance Sheet, the Sellers may either
inform the Purchasers in writing that the Closing Date Statement is acceptable or object thereto in writing, setting forth each of its objections (the “Sellers Objections”). Any items included in the Closing Date Statement
which are not disputed by the Sellers in the Sellers Objections (other than items necessary to offset an issue raised in the Sellers Objections) shall be deemed agreed to by the Sellers. If the Sellers deliver the Sellers Objections and the parties
do not resolve all such Sellers Objections on a mutually agreeable basis within ten (10) Business Days after the Purchasers’ receipt of the Sellers Objections, any Sellers Objections as to which the Purchasers and the Sellers cannot agree
upon may be submitted by either the Purchasers or the Sellers to the Dallas, Texas office of Hein & Associates LLP (the “Designated Accounting Firm”) for resolution as provided herein; provided, however, if such
accounting firm is unable or unwilling to serve as the Designated Accounting Firm, then the disputed Sellers Objections shall be submitted to an accounting firm that is mutually acceptable to the Sellers and the Purchasers. If the Sellers and the
Purchasers are unable to agree on a mutually acceptable Designated Accounting Firm, then the Designated 



  
 14 










	 	
Accounting Firm shall be an independent accounting firm of regionally or nationally recognized reputation which shall be selected by lot after each of the Sellers and the Purchasers have each
proposed two (2) firms and excluded one (1) firm proposed by the other. Subject to Section 2.6(f), the Designated Accounting Firm shall have the power, authority and duty to resolve any outstanding Sellers Objections and the
decision of the Designated Accounting Firm shall be final and binding upon the parties. Upon the agreement of the parties or the decision of the Designated Accounting Firm, the Closing Date Statement, as adjusted in accordance with this
Section 2.6, if necessary, shall be final and conclusive with respect to the calculation of the Final Purchase Price, including, without limitation, the calculation of Working Capital as of the Closing Date. If the Seller fails to
deliver any Sellers Objections to the Purchasers within the first fifteen (15)-day period referred to above, the Closing Date Statement delivered by the Purchasers and the calculations set forth therein shall be final and binding on the parties.


  

	vi.	In resolving any disputed item, the Designated Accounting Firm (i) shall be bound by the provisions of this Section 2.6, (ii) may not assign a
value to any item greater than the highest value claimed for such item or less than the lowest value for such item claimed by either the Purchasers or the Sellers, (iii) shall restrict its decision to such items included in the Sellers
Objections which are then in dispute, (iv) may review only the written presentations of the Purchasers and the Sellers in resolving any matter which is in dispute and (v) shall render its decision in writing within thirty
(30) calendar days after the disputed items have been submitted to it. Upon the resolution of all Sellers Objections, the Final Closing Date Balance Sheet, Working Capital as of the Closing Date and the determination of the Final Purchase Price
shall be revised to reflect the resolution. If the Sellers make any Sellers Objections, the fees, costs and expenses of the Designated Accounting Firm shall be paid (i) by the Sellers if the Sellers Objections are resolved in favor of the
Purchasers, or (ii) by the Purchasers if the Sellers Objections are resolved in favor of the Sellers. If the Sellers Objections are resolved part in favor of the Sellers and part in favor of the Purchasers, such fees, costs and expenses
shall be shared by the Purchasers and the Sellers in inverse proportion to the aggregate amount of the Sellers Objections resolved in favor of the Sellers compared to the aggregate amount of the Sellers Objections resolved in favor of the
Purchasers. 

  

	vii.	If the Final Purchase Price as finally determined in accordance with this Section 2.6 exceeds the Initial Purchase Price, the Purchasers shall pay the
amount of the difference in cash to the Sellers within five (5) Business Days after such final determination. If the Final Purchase Price as finally determined in accordance with this Section 2.6 is less than the Initial Purchase
Price, the Sellers shall deliver an amount of the difference in cash to the Purchasers within five (5) Business Days after such final determination; provided, however, that by notice to the other party, either party may elect to have all or any
portion of any amount to which the Purchasers may be entitled to receive under this Section 2.6(g) released from the Escrow Fund, in which event the Purchasers and the Sellers shall instruct the Escrow Agent to release such amount from
the Escrow Fund to the Purchasers. 

 g. Allocation of Purchase Price. The Purchasers and the Sellers agree
that the Final Purchase Price and the amount of Assumed Liabilities that are liabilities for income tax purposes shall be allocated for federal income tax purposes among the Purchased Assets as shall be determined by the parties in


  
 15 









 
accordance with this Agreement (the “Allocation Schedule”). The Allocation Schedule shall be prepared in accordance with Section 1060 of the Code and the Treasury
Regulations. The amount of the Purchase Price allocated to the fixed assets will be the tax book value of such assets as of the Closing. The Purchasers and the Sellers will jointly prepare the Allocation Schedule at or prior to Closing. If the
Initial Purchase Price differs from the Final Purchase Price, then the difference will be allocated proportionally among the categories set forth in the Allocation Schedule other than the amount allocated to the fixed assets, which will not change.
Unless otherwise required by applicable Law, the Purchasers and the Sellers agree to act, and cause their respective Affiliates to act, in accordance with the computations and allocations contained in the Allocation Schedule in any relevant Tax
Returns or similar filings (including any forms or reports required to be filed pursuant to Section 1060 of the Code (the “1060 Forms”)), to cooperate in the preparation of any 1060 Forms, to file such 1060 Forms in the
manner required by applicable Law and to not take any position inconsistent with such Allocation Schedule upon examination of any Tax Returns, in any litigation or otherwise. 
 h. Allocation of Purchased Assets Among Purchasers. Notwithstanding anything to contrary in Article II hereof, the Purchased Assets (and the Assumed Liabilities related to such Purchased Assets)
shall be allocated to the Purchasers such that any and all accounts receivable, inventory, rolling stock identified on Schedule 2.8 hereto as prepared by Purchasers, frac tanks and the Permits to Inject Fluid into a Reservoir Productive of
Oil and Gas or related permits issued by the Railroad Commission of Texas shall be allocated and held by Frontier Tank, or with respect to such Permits, an Affiliate designated by Frontier Tank, and all other Purchased Assets (and Assumed
Liabilities related to such Purchased Assets), including but not limited to all disposal wells and rights thereto, Tangible Personal Property and fixed assets, Property, Seller IP and Transferred Contracts, shall be allocated and held by Frontier
Disposal.

Ancillary Agreements to which each Seller is a party constitute the legal, valid and binding obligation of such Seller enforceable against such Seller in accordance with their respective terms, except as the enforceability thereof may be limited by

currently proposed to be conducted. All of the Seller IP is subsisting, valid, and enforceable. 
 ii. Neither the Sellers, nor
the conduct of the business of the Sellers as it has been conducted, is currently conducted, or is currently proposed to be conducted, infringes, misappropriates or otherwise violates the intellectual property rights of any third party and, except

or impose any additional restriction on the Sellers under any Contract granting rights to any Intellectual Property. Except as set forth on 

  
 20 









 
Schedule 2.1(a), all Contracts granting the Sellers rights to any Intellectual Property used or proposed to be used with respect to, or otherwise embodied by the operation, products,

other confidential and proprietary information owned or used by the Sellers, no loss or expiration of any Intellectual Property owned by the Sellers is threatened, pending or reasonably foreseeable (except for patents expiring at the end of their

 i. Financial Statements. 
 i. Attached to Schedule 4.9(a) hereto are copies of each Seller’s (i) Historical Audited Financial Statements and (ii) unaudited financial statements (balance sheet, statement
of operations, statement of cash flows and changes in stockholders’ equity) as at, and for the nine-month period ended September 30, 2012 (collectively, the “Seller Financial Statements”). The Seller Financial
Statements comply in all material respects as to form with applicable accounting requirements as of their respective dates, and were prepared from the books and records of the Sellers and converted in order to comply with generally accepted
accounting principles in the United States (“GAAP”) (except that the unaudited financial statements are not prepared in accordance with GAAP). The Seller Financial Statements fairly present the financial condition and
operating results of the Sellers as of the dates, and for the periods, indicated therein, in all material respects, subject, in the case of unaudited financial statements, to normal year-end audit adjustments (which adjustments would not be
material, individually or in the aggregate). Each Seller maintains a standard system of accounting established and administered in accordance with sound accounting principles. 
 ii. The accounts receivable shown on the unaudited balance sheets of each Seller as of September 30, 2012 included in the Seller Financial Statements (the “Seller Balance
Sheets”) and accounts receivable since the date thereof arose from bona fide transactions in the ordinary course of business and consistent with past practice and are not subject to discount. Subject to a reserve of two percent (2%),
such accounts receivable are uncontested, unconditional obligations of the account debtors and are not in dispute or subject to any valid defense, offset, counterclaim or agreement which varies with the terms thereof. Schedule 4.9(b) contains
a complete and accurate list of all accounts receivable of the Sellers, which list sets forth the aging of such accounts receivable. Since the date of the Seller Balance Sheets (the 

  
 21 









 
“Balance Sheet Date”), each Seller has continued all receivables and payables production practices in accordance with the ordinary course of business and consistent with
prior period practice and has not engaged in (A) any practice intended to have the effect of accelerating to pre-Closing periods collections of receivables that would otherwise be expected (based on past practice) to be made in post-Closing
periods or (B) any practice intended to have the effect of postponing to post-Closing periods payments by such Seller that would otherwise be expected (based on past practice) to be made in pre-Closing periods. 

iii. Schedule 4.9(c) lists all inventory of each Seller as of the date hereof. 

iv. All prepayments by the customers of any Seller for services to be performed by such Seller have been validly received for services
currently scheduled or anticipated to be performed and, to the Knowledge of the Sellers, no such prepayments are expected to be refunded or returned.

vii. Since the Balance Sheet Date, each Seller has continued to pay all accounts and notes payable in accordance with the ordinary course
of business and consistent with prior period practice and the payment terms of its suppliers, and none of such payables is more than 30 days past its scheduled due date. 
 viii. Each Sellers has devised and maintains a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with
management’s general or specific authorization and such Seller’s policies and procedures, and (ii) transactions are recorded as necessary (A) to permit preparation of financial statements in accordance with sound accounting
practices or any other criteria applicable to such statements and (B) to maintain accountability for material assets. 

ix. Other than the engagement of Turner, Stone & Company, LLP, during the periods covered by the Seller Financial Statements,
neither Seller has changed its independent accountants or had any disagreement with such accountants on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure that if not resolved to the
satisfaction of such accountants would have caused such accountants to make reference to the subject matter of the disagreements in connection with its report. 
 j. Books and Records. The Books and Records and other similar records of the Sellers have been provided or made available to the Purchasers or its counsel prior to the execution of this Agreement.
The minute books contain an accurate record of all actions taken at all meetings and by all written consents in lieu of meetings of the managers, members and related committees of the Sellers from the date of formation through the date hereof. The
Books and Records of the Sellers (i) are

threatened by any Tax Authority or (ii) of which any Seller is otherwise aware. There are no Encumbrances for Taxes upon any of the assets or properties of the Sellers including, without limitation, any of the Purchased Assets other than an

Seller. 
 v. There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any Tax
Returns required to be filed by, or that include or are treated as including, any Seller or with respect to any Tax assessment or deficiency affecting any Seller.

similar Law). 
 xii. None of the Sellers will be required to include any item of income in, or exclude any item of deduction
from, taxable income for the taxable period (or portion thereof) ending after the Closing Date as a result of any: 
 1. change in method of accounting for a taxable period ending on or prior to the Closing Date; 
 2. “closing agreement” as described in Code Section 7121 (or any corresponding or similar provision of state, local or foreign income Tax Law) executed on or prior to the Closing Date; or

in all material respects in accordance with each of the requirements of Section 4980B of the Code and Part 6 of Subtitle B of Title I of ERISA. 

  
 27 









 viii. No condition, agreement or Employee Benefit Plan provision limits the right of any
Seller to amend, cut back or terminate any benefit Plan (except to the extent such limitation arises under ERISA or the Code). 

ix. No Seller has participated in any voluntary compliance or self-correction program established by the IRS under the Employee Plans

utilities are adequate for the operation of the business conducted thereon. Notwithstanding the foregoing or anything else in this Agreement to the contrary, each Purchaser acknowledges and

endorsement, each Title Defect prior to Closing; provided, in no event shall Sellers be required to pay for such endorsements in excess of an aggregate of $2,600. Without limiting the foregoing, the Sellers shall cause to be removed, at Closing, any
Title Defects which are voluntary liens, mortgages or security interests, and any standby fees, annual taxes and assessments by Governmental Authorities, and all mechanic’s and materialmen’s liens. If the Sellers are unable to remove any
Title Defects after receiving the Purchasers’ notice of Title Defects or to satisfy any other requirements from the Purchasers or the Title Company related to the Title Commitment, then the Sellers may notify the Purchasers that any such Title
Defect will not be removed and in such event the Purchasers may either (i) terminate this Agreement (in which event the Sellers and the Purchasers will be relieved from any further obligations hereunder), or (ii) accept such Title Defects
and continue to Closing, in which event such Title Defects will be Closing Encumbrances. Any Encumbrance or other matters contained in the title policy issued pursuant to the Title Commitment and in the final Survey at Closing (the
“Closing Encumbrances”) shall be deemed approved by the Purchasers and the Property will be conveyed to Frontier Disposal subject to the Closing Encumbrances. The Purchasers shall be responsible for all costs
and expenses related to the Title Commitment, the title policy or title policies and the Surveys.

 f. Consent to Employment. As and to the extent necessary to permit each Transferred
Employee to whom a Purchaser or its Affiliate offered employment to accept employment with such Purchaser, to engage in the Business as it may be conducted by such Purchaser from and after the Closing Date and to exploit the Purchased Assets for
commercial purposes, subject to the Closing, from and after the Closing Date, each Seller for itself and its Affiliates, hereby waives any rights it may have under or by virtue of any employment agreement, offer letter or arrangement with such
Persons. 
 g. Risk of Loss. Sellers shall, jointly and severally, bear all risk of loss of or damage (other than
ordinary wear and tear) to any Purchased Asset at all times prior to the Closing Date. Between the date of this Agreement and the Closing Date, if any material Purchased Asset is lost, materially damaged or destroyed (other than ordinary wear and
tear), Sellers shall, at their option: either (i) replace or restore such Purchased Asset to at least as good condition as existed on the date of this Agreement; or (ii) pay over and assign to the Purchasers all insurance proceeds payable
as a result of the occurrence of the event resulting in such loss or damage (to the extent not used to restore or replace the Purchased Assets prior to the Closing) and all deductibles related to such insured loss or damage. To the extent that such
insurance proceeds and deductibles are not sufficient to restore or replace such Purchased Asset, Sellers shall pay to the Purchasers the difference between such amount and the fair market value of the Purchased Asset on the date of loss. This
Section 6.7 shall in no way limit the Purchasers’ rights under Section 9.1. Notwithstanding the foregoing, the Sellers will in no event be required to pay to the Purchasers in excess of an aggregate of $50,000 (the
“Risk of Loss Cap”) pursuant to this Section 6.7. In the event that Sellers’ aggregate obligations under this Section 6.7 would exceed the Risk of Loss Cap and Sellers notify the Purchasers that
Sellers will not pay the Purchasers an amount in excess of the Risk of Loss Cap, then the Purchasers may either (i) agree to limit its recovery under this Section to the Risk of Loss Cap and continue to Closing, or (ii) terminate this
Agreement, in which event the Purchasers and Sellers will be relieved from any further obligations under this Agreement. 
 h.
Negative Cash Balances. No later than the Closing, each Seller shall promptly take action to eliminate any negative cash balances of such Seller. 
 i. Nonassignability of Certain Assets. To the extent that any Contract, Permit or other right included in the Purchased Assets is not capable of being assigned or transferred without the consent or
waiver of the other party thereto, or any third person (including a Governmental Authority), or if such assignment or transfer or attempted assignment or transfer would constitute a breach thereof or a violation of


  
 42 









 
any Law or is otherwise not practicable, this Agreement shall not constitute an assignment, transfer or sublease thereof, or an attempted assignment, transfer or sublease thereof prior to the
time that the appropriate consent or waiver is obtained. From and after the Closing, to the extent that any Contract, Permit or other right included in the Purchased Assets is not assigned hereunder (the “Non-Assigned
Assets”), the Sellers shall preserve and provide to the Purchasers the benefit (including the economic benefit thereof) of the Non-Assigned Assets unless it would constitute a breach thereof or a violation of Law; provided, however,
nothing in this Section 6.9 shall limit the Purchasers’ rights under Section 9.1. 
 j. Accounts
Payable. From time to time prior to the Closing, each Seller shall cause all accounts payable of such Seller to be paid in a timely manner such that no accounts payable of such Seller are more than ninety (90) days past their respective

and will constitute valuable, special and unique property of the Purchasers. Each of the Sellers and the Shareholders agree that (subject to the Closing) from and after the Closing Date for a period of five (5) years (such five (5) year
period is hereinafter referred to as the “Restricted Period”), such Seller or Shareholder will not, directly or indirectly, without the prior written consent of the Purchasers, disclose, reveal, divulge or communicate to any
Person other than authorized officers, directors and employees of the Purchasers or their Subsidiaries, or use or otherwise exploit for such Seller’s or Shareholder’s own benefit or for the benefit of anyone other than the Purchasers or
their Subsidiaries, any Confidential Information; provided, however, that such Restricted Period will be extended by and for the duration of any period of time during which such Seller or Shareholder is in violation of any provision of this
Section 8.1(a). Each Seller and Shareholder shall not have any obligation to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by Law; provided, however, that in the
event disclosure is required by applicable Law, such Seller or Shareholder shall, to the extent reasonably possible, provide the Purchasers with prompt notice of such requirement prior to making any disclosure so that the Purchasers may seek an
appropriate protective order. If a protective order or other remedy is not available, or if the other party waives compliance with the provisions of this Section 8.1(a), the party receiving the


  
 48 









 
request for disclosure or its representatives, as the case may be, may disclose to the Person requiring disclosure only that portion of the Confidential Information which such party is legally
required to disclose. For purposes of this Section 8.1, “Confidential Information” shall mean any confidential information with respect to the Business, including, without limitation, methods of operation,
customers, customer lists, products and services, proposed products and services, former products and services, proposed, pending or completed acquisitions of any company, division, product line or other business unit, prices, fees, costs, plans,
designs, technology, inventions, trade secrets, know-how, software, marketing methods, policies, plans, personnel, suppliers, markets or other specialized information or proprietary matters. The term “Confidential
Information” does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement, or (ii) becomes generally available to the
public other than as a result of a disclosure by any Seller or Shareholder not otherwise permissible thereunder. 
 ii. Each of
the Sellers and the Shareholders hereby agree that (subject to the Closing), during the Restricted Period, such Seller or Shareholder will not, directly or indirectly (including without limitation through Subsidiaries, Affiliates or Associates or by
contract), as a partner, joint venturer, employer, employee, consultant, shareholder, principal, manager, agent or otherwise, own, manage, operate, finance, join, control, participate or lend money or such Seller’s or Shareholder’s
reputation to any business, whether in corporate, limited liability company or partnership form or otherwise, which in any way engages in any business that competes with the Business as carried on or proposed to be carried on at the Closing Date in
the State of Texas; provided, however, that (i) nothing herein shall be construed to prevent such Seller or Shareholder from holding as a passive investment not more than one percent (1%) of the shares in any company whose shares are
quoted on any stock exchange or inter-dealer quotation system, (ii) the foregoing provisions shall not in any way limit or mitigate such Seller’s or Shareholder’s confidentiality obligations herein and (iii) such Restricted
Period will be extended by and for the duration of any period of time during which such Seller or Shareholder is in violation of any provision of this Section 8.1(b). 

iii. Each of the Sellers and the Shareholders hereby agree that (subject to the Closing), during the Restricted Period, such Seller or
Shareholder will not, directly or indirectly (including without limitation through Subsidiaries, Affiliates or Associates or by contract), as a partner, joint venturer, employer, employee, consultant, shareholder, principal, manager, agent or
otherwise, (i) induce or attempt to induce, or cause any officer, director or employee of a Purchaser or any of its Subsidiaries to leave the employ of such Purchaser or such Subsidiary, or in any way materially interfere with the relationship
between such Person, on the one hand, and any such officer, director or employee, on the other hand; or (ii) induce, or attempt to induce, any customer, salesperson, supplier, vendor, representative, agent, licensee or other Person transacting
business with a Purchaser or such Subsidiary to reduce or cease doing business with such Person, or in any way to interfere with the relationship between any such customer, salesperson, supplier, vendor, representative, agent, licensee or business
relation, on the one hand, and such Purchaser or such Subsidiary, on the other hand; provided, however, that such Restricted Period will be extended by and for the duration of any period of time during which such Seller or Shareholder is in
violation of any provision of this Section 8.1(c). The foregoing restrictions shall include any Person who was an officer, director, employee, customer, salesperson, supplier, vendor, representative, agent, licensee or other Person
transacting business with the Sellers within six (6) months prior to the Closing Date or with a Purchaser or any of its Subsidiaries during such Restricted Period. 

  
 49 









 iv. The parties hereto specifically acknowledge and agree that the remedy at law for any
breach of the foregoing will be inadequate and that the Purchasers, in addition to any other relief available to it, shall be entitled to temporary and permanent injunctive relief. 

v. Each of the Sellers and the Shareholders hereby further acknowledge and agree that, in view of the nature of the Business and the
business objectives of the Purchasers in acquiring the Purchased Assets and the consideration paid to the Sellers therefor, the scope of business, territorial and time limitations contained in this Section 8.1 are reasonable and properly
required for the adequate protection of the Purchasers. The parties hereto intend that the covenants of this Section 8.1 be (i) enforceable to the maximum extent permitted by Law, and (ii) severable, and, if any reviewing court
determines that any such covenant is unenforceable, invalid or of excessive duration or scope, such determination shall not affect the enforceability of any other covenants herein; further, in the event of any such determination, the parties
authorize such court to (i) reform the unenforceable, invalid or excessive provisions, and (ii) impose such restrictions as reformed, as it deems reasonable. The Purchasers may, upon written notice to and without the consent of any Seller
or Shareholder, reduce the scope of the covenants of this Section 8.1 that apply to such Seller or Shareholder, if the Purchasers deems such reduction in scope is necessary to enforce such covenants. 

vi. Each Seller and each Shareholder hereby acknowledge that such Seller’s or Shareholder’s covenants made in this
Section 8.1 are in addition to, and do not replace or amend, any non-competition covenants which may have heretofore been agreed to, or may hereafter be agreed to, with the Purchasers or their Subsidiaries, and in the event the covenants
in this Section 8.1 are in any way found unenforceable or invalid or are in any way limited or reformed, such other covenants shall not be affected thereby. 
 b. Post-Closing Notifications. The Purchasers and the Sellers will, and each will cause their respective Affiliates to, comply with any post-Closing notification or other requirements, to the
extent then applicable to such party, of any Law of any Governmental Authority having jurisdiction over the Purchasers or the Sellers.

 i. Except for all motor vehicle and related sales,
transfer and title taxes related to the transfer of the Purchased Assets and all closing costs related to the Property (all of which will be paid by the Purchasers), all sales, use, transfer, stamp, conveyance, value added or other similar Taxes,
duties, excises or governmental charges imposed by any Governmental Authority, domestic or foreign, and all recording or filing fees, notarial fees and other similar costs of Closing with respect to the transactions contemplated hereby will be borne

 ii. Following the Closing, each party hereto shall afford the other parties, upon reasonable
advance notice, reasonable access that does not unreasonably interfere with the affording party’s operation of its business, to the books and records relating to the Purchased Assets and Assumed Liabilities in the affording party’s
possession and the right to make copies and extracts therefrom, to the extent that such access or copies may be reasonably required by the requesting party in connection with the preparation of its Tax Returns. If, in order to properly prepare such
Tax Returns, it is necessary that a requesting party be furnished with additional information, documents or records relating to the Purchased Assets or Assumed Liabilities not referred to in the foregoing sentence, then the affording party shall use
commercially reasonable efforts to furnish or make available, on a timely basis, such information, documents or records (or copies thereof) at the requesting party’s cost and expense. Notwithstanding anything to the contrary in this Agreement,
each party will, at its own expense, control any audit or examination by any Governmental Authority, and have the exclusive right to initiate any Claim for refund or amended return, and contest, resolve and defend against any assessment, notice of
deficiency or other adjustment or proposed adjustment of Taxes (“Tax Proceedings”) for any taxable period for which that party is charged with payment responsibility under this Agreement. In the case of any Tax Proceedings
relating to a period that begins before the Closing Date and ends after the Closing Date, the Purchasers will control such Tax Proceedings and will consult in good faith with the Sellers as to the conduct of such Tax Proceedings; provided, that in
no event will the Purchasers settle any Tax Proceeding relating to any period that begins and ends on or before the Closing Date in a manner that would adversely affect Sellers, without the prior written consent of the Sellers, which consent may not
be unreasonably withheld, conditioned or delayed. 
 d. Name Change. Each Seller shall cease using the names
“L & R Tank Trucks,” “Stark & Stark Equipment” or any derivative thereof and within ten (10) Business Days after the Closing Date, each Seller shall (a) file an amendment to its certificate of
formation to reflect such change and (b) provide evidence of such name change to the Purchasers. Each Seller shall cooperate with the Purchasers to coordinate such filings to ensure that all rights to the names “L & R Tank
Trucks” and “Stark & Stark Equipment” vests solely in the Purchasers. 
 e. Refunds and
Remittances. After the Closing: (i) if any Seller receives any refund or other amount that is a Purchased Asset or is otherwise properly due and owing to any Purchaser in accordance with the terms of this Agreement, then such Seller
promptly shall remit, or shall cause to be remitted, without setoff, such amount to the applicable Purchaser and (ii) if any Purchaser or any of its Affiliates receive any refund or other amount that is an Excluded Asset or is otherwise
properly due and owing to any Seller in accordance with the terms of this Agreement, then such Purchasers promptly shall remit, or shall cause to be remitted, without setoff, such amount to the applicable Seller. 

f. Public Announcements. Upon consummation of the transactions contemplated hereby, except as required by applicable Law or stock
exchange or similar rules, neither the Purchasers nor the Sellers shall disclose the terms of or the existence of this Agreement (except to advisors, investors and financing sources who have a need to know or who are otherwise subject to a
confidentiality restriction) without the prior written consent of the other party.

agreements and other documents and take such other actions as another party may reasonably request or as may be necessary or appropriate to consummate or implement the transactions contemplated by this Agreement or to evidence such events or
matters; provided, however, that no party shall be required to execute an amendment hereof or to waive any of its rights or any breach hereunder. In addition, the Purchasers agree to cooperate reasonably with the Sellers and the Shareholders to the

supplemented the Schedules pursuant to Section 6.4 and the matter disclosed, updated, amended or modified would have the effect of causing the conditions in Section 7.1(a) to not be satisfied; or (v) if Sellers are
unable to remove all Title Defects in accordance with Section 6.5; 
 iv. by the Sellers if (i) at any time
there has been a material misrepresentation, material breach of warranty or material breach of covenant on the part of any Purchaser in any of the representations, warranties or covenants under this Agreement which breach is not curable, or if
curable, is not cured within ten (10) days after written notice of such breach is given to the Purchasers; or (ii) any of the conditions set forth in Section 7.2 hereof shall not have been met within thirty (30) days after
the date hereof or is otherwise incapable of being satisfied; or 
 v. by the Purchasers or the Sellers, if (i) the
calculation of the Estimated Working Capital Adjustment pursuant to Section 2.6(b) results in an adjustment (whether an increase or a decrease) to the Initial Purchase Price of more than $150,000; (ii) the party or parties electing
to terminate this Agreement pursuant to this Section 9.1(e) provides the other party or parties with two (2) Business Days’ prior written notice of its intent to terminate this Agreement pursuant to this
Section 9.1(e), and (iii) after receipt of such notice and prior to the time of termination of this Agreement set forth in such notice, the non-terminating party has not agreed in writing to increase or decrease the amount of the
Initial Purchase Price in favor of the terminating party in order to cure the termination right under this Section 9.1(e) by such amount that would cause an adjustment of less than $150,000 (whether an increase or decrease) to the
Initial Purchase Price under clause (i) of this Section 9.1(e). 
 The party desiring to terminate this Agreement
pursuant to this Section 9.1 shall give written notice of such termination to the other party in accordance with Section 11.5 hereof. 

  
 53 









 b. Effect of Termination. If this Agreement is terminated pursuant to
Section 9.1 hereof, this Agreement shall become void and of no effect with no liability on the part of any party hereto, except that the agreements contained in this Section 9.2 and Article XI hereof shall survive the
termination of this Agreement. Notwithstanding the foregoing, nothing in this Section 9.2 shall relieve any party to this Agreement of liability for a willful misrepresentation or breach of any provision of this Agreement and provided
further that if it shall be judicially determined that the termination of this Agreement was caused by a willful misrepresentation or breach of this Agreement, then, in addition to other remedies at law or equity for breach of this Agreement, the
party found to have willfully breached this Agreement shall be responsible for payment or reimbursement of the other parties’ costs, fees and expenses related to the negotiation, preparation and execution of this Agreement and related consents,
including attorneys’ fees and expenses. 
 10. 

INDEMNIFICATION 
 a. Survival of Representations, Warranties and Covenants. 
 i. Except as to
(i) the representations and warranties contained in Sections 4.2 and 5.2 (Authority; Enforceability); 4.3 and 5.3 (No Conflicts); 4.24 and 5.6 (No Brokers or Finders); 5.4 (Legal Proceedings);
4.1 (Organization and Qualification); 4.6 (Capitalization; Subsidiaries); 4.7 (Litigation; Orders); the first sentence of 4.15 (Assets); and 5.1 (Organization; Standing and Power), which shall in each case survive
the Closing indefinitely (the representations and warranties described in this clause (i) collectively being, the “Fundamental Representations”), (ii) the representations and warranties contained in
Sections 4.13 (Taxes); 4.14 (Benefit Plans; ERISA); 4.18 (Labor Matters); and 4.19 (Environmental Matters), which shall in each case survive the Closing and remain in effect until the expiration of forty-eight
(48) months from the Closing Date (the representations and warranties described in this clause (ii) collectively being, the “Compliance Representations”), and (iii) claims for indemnification related to fraud,
which shall survive the Closing and remain in effect indefinitely, the representations and warranties contained in this Agreement, any Ancillary Agreement or any other certificate delivered in connection herewith or therewith shall survive the
Closing until the expiration of twenty-four (24) months from the Closing Date. Any claim for indemnification with respect to any of such matters which is not asserted by notice given as herein provided relating thereto within such specified
period of survival may not be pursued and is hereby irrevocably waived after such time. Any claim for an Indemnifiable Loss asserted within such period of survival as herein provided will be timely made for purposes hereof. 

ii. Unless a specified period is set forth in this Agreement (in which event such specified period will control), the covenants in this
Agreement will survive the Closing indefinitely. 
 b. Limitations on Liability. 

i. For purposes of this Agreement, (i) “Indemnity Payment” means any amount of Indemnifiable Losses required
to be paid pursuant to this Agreement, (ii) “Indemnitee” means any Person entitled to indemnification under this Agreement, 

  
 54 









 
(iii) “Indemnifying Party” means any Person required to provide indemnification under this Agreement, (iv) “Indemnifiable Losses” means
any and all damages, losses, Liabilities, obligations, diminution in value, costs and expenses, and any and all claims, demands or suits (by any Person, including without limitation any Governmental Authority), including without limitation the costs
and expenses of any and all actions, suits, proceedings, demands, assessments, judgments, settlements and compromises relating thereto and including reasonable attorneys’ fees and expenses in connection therewith, and (v) “Third
Party Claim” means any claim, demand, action or proceeding made or brought by any Person who or which is not a party to this Agreement or an Affiliate of a party to this Agreement. 

ii. Subject to Section 10.2(d) below, the Purchasers and each of their respective directors, managers, officers, Affiliates,
employees, agents, stockholders, members and representatives, will not be entitled to make a claim against the Sellers or any Shareholder in respect of any Indemnifiable Losses under Section 10.3(a)(i) unless and until the aggregate
amount of claims for Indemnifiable Losses under Section 10.3(a)(i) exceeds $150,000, in which event the Purchasers will only be entitled to make a claim for Indemnifiable Losses to the extent such Indemnifiable Losses exceed $150,000.

 iii. Subject to Section 10.2(d) below, neither the Sellers nor the Shareholders (individually or in the
aggregate) shall have any liability for Indemnifiable Losses pursuant to Section 10.3(a)(i) or (iii) in excess of a cap equal to twenty percent (20%) of the Final Purchase Price or pursuant to Sections 10.3(a)(iv)
in excess of a cap equal to the Final Purchase Price. 
 iv. Anything to the contrary herein notwithstanding the limitations set
forth in Sections 10.2(b) and (c) shall not apply to Indemnifiable Losses arising out of, relating to or incurred as a result of fraud, intentional misrepresentations, intentional acts or willful misconduct. 

v. Each Indemnitee agrees to use its best efforts to pursue applicable claims under or pursuant to any insurance coverage in connection
with any Indemnifiable Loss. If the amount of any Indemnifiable Loss, at any time subsequent to the making of an Indemnity Payment, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any
claim, recovery, settlement or payment by or against any other Person, in each case which is actually received by the Indemnitee, the amount of such reduction, less any costs, expenses, premiums or taxes incurred in connection therewith will
promptly be repaid by the Indemnitee to the Indemnifying Party, and net of any costs or expenses incurred in connection with collecting such amount (including any increased premium costs resulting therefrom); provided, however, that
the foregoing shall not (i) require an Indemnitee to proceed or seek action or recovery from any such third party as a requirement hereunder or as a condition to seeking or recovering indemnification from any Indemnifying Party hereunder, or
(ii) be construed or interpreted as a guaranty of any level or amount of insurance recovery with respect to any Indemnifiable Losses hereunder or as a requirement to maintain any insurance or to make any claim for insurance as a condition to
any indemnification hereunder. 
 vi. Each of the representations and warranties that contains any “Knowledge,”
“Material Adverse Effect,” “material” or similar materiality qualifications shall be read as though such qualifications were not contained therein for the purposes of determining whether or not an Indemnitee is entitled to
indemnification pursuant to this Article X or the amount of Indemnifiable Losses to which such Indemnitee may be entitled under this Article X. 

  
 55 









 vii. In no event will any Purchaser be entitled to any Indemnifiable Loss to the extent such
Purchaser has already recovered the economic benefit of such loss pursuant to Section 2.6. 
 c.
Indemnification. 
 i. Subject to this Article X, the Sellers and the Shareholders, jointly and severally, agree to
indemnify and hold harmless the Purchasers and their respective directors, managers, officers, Affiliates, employees, agents, stockholders, members and representatives from and against any and all Indemnifiable Losses to the extent relating to,
resulting from or arising out of: 
 1. any breach of any representation or warranty, other than the Fundamental
Representations and the Compliance Representations, of any Seller under the terms of this Agreement, any Ancillary Agreement, or any certificate delivered pursuant hereto (after giving effect to any supplements to the Disclosure Schedules);

 2. any breach of any Fundamental Representation or Compliance Representation of any Seller under the terms of
this Agreement (after giving effect to any supplements to the Disclosure Schedules); 
 3. any breach or
nonfulfillment of any agreement or covenant of any Seller or any Shareholder under the terms of this Agreement or any Ancillary Agreement (after giving effect to any supplements to the Disclosure Schedules); and 

4. the payment and performance of any Excluded Liabilities. 

ii. Subject to this Article X, each Purchaser agrees to indemnify and hold harmless the Sellers and the Shareholders and their
respective directors, managers, officers, Affiliates, partners, employees, agents, shareholders and representatives from and against any and all Indemnifiable Losses to the extent relating to, resulting from or arising out of: 

1. any breach of any representation or warranty, other than the Fundamental Representations, of any Purchaser under the
terms of this Agreement, any Ancillary Agreement, or any certificate delivered pursuant hereto; 
 2. any breach
of any Fundamental Representation of any Purchaser under the terms of this Agreement; 
 3. any breach or
nonfulfillment of any agreement or covenant of any Purchaser under the terms of this Agreement or any Ancillary Agreement; and 
 4. the payment and performance of the Assumed Liabilities. 

  
 56 









 d. Recourse Against Escrow Fund. In the event of any claim by any Purchaser against
the Sellers and the Shareholders for Indemnifiable Losses under Sections 10.3(a) such Purchaser shall seek payment first out of the Escrow Fund; and then, if the Escrow Fund has been reduced to zero pursuant to this Section 10.4,
such Purchaser shall then be entitled to seek payment directly from the Sellers or Shareholders for Indemnifiable Losses under Section 10.3(a), subject to the terms and provisions of this Article X. 

e. Defense of Claims. 
 i. If any Indemnitee receives notice of assertion or commencement of any Third Party Claim against such Indemnitee with respect to which an Indemnifying Party is obligated to provide indemnification under
this Agreement, the Indemnitee will give such Indemnifying Party reasonably prompt written notice thereof. Such notice will describe the Third Party Claim in reasonable detail, will include copies of all material written evidence thereof and will
indicate the estimated amount, if reasonably practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in, or, by giving written notice to the Indemnitee, to
assume, the defense of any Third Party Claim at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel if: (i) the Indemnifying Party acknowledges its obligation to indemnify the Indemnitee for any
Indemnifiable Losses resulting from such Third Party Claim, subject to the limitations set forth in Sections 10.2(b) and 10.2(c), (ii) such Third Party Claim involves (and continues to involve) solely monetary damages which
are not reasonably likely to exceed the applicable amount (if any) in Section 10.2(c); (iii) such Third Party Claim does not relate to or arise in connection with any criminal action or the Indemnitee’s relationship with any
customer, supplier or employee; and (iv) the Indemnifying Party makes reasonably adequate provision to satisfy the Indemnitee of the Indemnifying Party’s ability to defend, satisfy and discharge such Third Party Claim (collectively, the
“Defense Conditions”). In such event, the Indemnifying Party shall from time to time apprise the Indemnitee of the status of the Third Party Claim and shall furnish the Indemnitee with such documents and information filed or
delivered in connection with such claim, Liability or expense as the Indemnitee may reasonably request. 
 ii. If, within ten
(10) calendar days after giving notice of a Third Party Claim to an Indemnifying Party pursuant to Section 10.5(a), an Indemnitee receives written notice from the Indemnifying Party that the Indemnifying Party has elected to assume
the defense of such Third Party Claim as provided in the last sentence of Section 10.5(a) and the Defense Conditions are satisfied, the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee
in connection with the defense thereof; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim within ten (10) calendar days after receiving written notice
from the Indemnitee that the Indemnitee believes the Indemnifying Party has failed to take such steps, if the Indemnifying Party has not undertaken fully to indemnify the Indemnitee in respect of all Indemnifiable Losses relating to the matter,
subject to the limitations set forth in Sections 10.2(b) and 10.2(c), or if any of the Defense Conditions cease to be satisfied for any reason, the Indemnitee may assume its own defense, and the Indemnifying Party will be liable
for all costs or expenses paid or incurred in connection therewith (including reasonable attorneys’ fees), subject to the limitations set forth in Section 10.2(b) and 10.2(c), and Indemnitee shall have the right to compromise
or settle such Third Party Claim with the consent of the Indemnifying Party (which consent shall not be 

  
 57 









 
unreasonably withheld). If the Defense Conditions are satisfied and the Indemnifying Party elects to assume and control the defense of a Third Party Claim as provided herein, then: (i) the
Indemnifying Party will not be liable for any settlement of such Third Party Claim effected without its consent, which consent will not be unreasonably withheld or delayed; (ii) the Indemnifying Party may settle such Third Party Claim without
the consent of the Indemnitee only if (A) all monetary damages payable in respect of the Third Party Claim are paid by the Indemnifying Party (subject to the limitations set forth in Sections 10.2(b) and 10.2(c)),
(B) the Indemnitee receives a full, complete and unconditional release in respect of the Third Party Claim without any admission or finding of obligation (other than the obligation to pay the settlement amount under such agreement), liability,
fault or guilt (criminal or otherwise) with respect to the Third Party Claim, and (C) no injunctive, extraordinary, equitable or other relief of any kind is imposed on the Indemnitee or any of its Affiliates; and (iii) the Indemnifying
Party may otherwise settle such Third Party Claim only with the consent of the Indemnitee, which consent will not unreasonably be withheld or delayed. Notwithstanding anything herein stated, the Indemnitee shall at all times have the right to fully
participate in such defense at its own expense directly or through counsel; provided, however, that the fees and expenses of such separate counsel shall be borne by the Indemnifying Party if (i) the Indemnifying Party has failed to assume the
defense within the period provided herein, (ii) there exists a conflict between the interests of the Indemnifying Party and the Indemnitee, (iii) a defense exists for the Indemnitee which is not available to the Indemnifying Party, or
(iv) the employment of such counsel at the expense of the Indemnifying Party has been specifically authorized by the Indemnifying Party in writing. If the Defense Conditions are not satisfied, the Indemnitee may assume the exclusive right to
defend, compromise or settle such Third Party Claim, but the Indemnifying Party will not be bound by any determination of a Third Party Claim so defended or any compromise or settlement effected without its consent (which may not be unreasonably
withheld or delayed); provided, that the Indemnitee will not be required to obtain any consent of the Indemnifying Party to the determination of such Third Party Claim (and will not prejudice its right to be indemnified with respect to such Third
Party Claim by determining such Third Party Claim) if the Indemnifying Party is disputing in any manner its obligation to indemnify the Indemnitee in respect of such Third Party Claim. 

iii. A failure to give timely notice or to include any specified information in any notice as provided in Sections 10.5(a) or
10.5(b) will not affect the rights or obligations of any party hereunder except and only to the extent that, as a result of such failure, any party which was entitled to receive such notice was deprived of its right to recover any payment
under its applicable insurance coverage or was otherwise materially damaged as a result of such failure. 
 iv. The Indemnifying
Party will have a period of fifteen (15) calendar days within which to respond in writing to any written claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third Party Claim (a “Direct
Claim”). If the Indemnifying Party does not so respond within such fifteen (15) calendar day period, the Indemnifying Party will be deemed to have rejected such claim, in which event the Indemnitee will be free to pursue such
remedies as may be available to the Indemnitee on the terms and subject to the provisions of this Article X. 

  
 58 









 f. Exclusive Remedy and Limitation of Certain Damages. From and after the Closing Date, as
between the Sellers, the Shareholders and the Purchasers, the parties agree that except for the Purchasers’ obligation to pay the Initial Purchase Price as provided for in Section 2.5 and except as otherwise provided for in
Section 2.6 and Section 8.3 and except for a party’s right to seek specific performance of covenants or an injunction to prevent a violation thereof (including as contemplated by Section 8.1(d)), and except
for a party’s rights under any Employment Agreement with any Shareholder, the sole and exclusive remedy of the parties hereto based upon, arising out of or otherwise in respect of the matters set forth in this Agreement or the other Ancillary
Agreements or arising out of the transactions contemplated hereunder or thereunder, including for any breach of or inaccuracy in any representation or warranty (other than claims for fraud or willful misconduct) are the indemnification obligations
set forth in this Article X. No party shall be entitled to recover against any other party under this Agreement for any indirect, incidental, consequential, exemplary, punitive, statutory or special damages unless such damages are the result
of actual fraud or intentional misrepresentation or are payable to a third party in connection with any Third-Party Claim. 
 g.
Strict Liability or Indemnitee Negligence. THE PROVISIONS IN THIS ARTICLE X SHALL BE ENFORCEABLE REGARDLESS OF WHETHER THE LIABILITY IS BASED UPON PAST, PRESENT, OR FUTURE ACTS, CLAIMS, OR LAWS (INCLUDING ANY PAST, PRESENT, OR FUTURE
ENVIRONMENTAL LAW (INCLUDING, BUT NOT LIMITED TO CERCLA), OCCUPATIONAL SAFETY AND HEALTH LAW, OR PRODUCTS LIABILITY, SECURITIES, OR OTHER LAW) AND REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM RELIEF IS SOUGHT) ALLEGES OR PROVES
THE SOLE, CONCURRENT, CONTRIBUTORY, OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING RELIEF, OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON THE PERSON SEEKING RELIEF. 
 11. 
 GENERAL PROVISIONS 

a. Expenses. Except as otherwise provided herein (including, without limitation, Section 2.6, Section 6.7,
Section 7.1(s), Article IX and Article X), whether or not the transactions contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement, the Ancillary Agreements and the
transactions contemplated hereby and thereby shall be paid by the party incurring such expenses.

Agreement may be amended or modified in whole or in part at any time by an agreement in writing among the Sellers, the Purchasers and the Shareholders. 

  
 59 









 c. Waiver. Any term or provision of this Agreement may be waived in writing at any
time by the Sellers, the Shareholders or the Purchasers, as applicable, as such waiver relates to a benefit of such party under this Agreement. Any waiver effected pursuant to this Section 11.3 shall be binding. No failure to exercise
and no delay in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude the exercise of any other right, power or privilege. No waiver of any
breach of any covenant or agreement hereunder shall be deemed a waiver of a preceding or subsequent breach of the same or any other covenant or agreement. The rights and remedies under this Agreement are in addition to all other rights and remedies,
whether at law, in equity or otherwise, that any party may have against another. 
 d. Cumulative Remedies. The rights
and remedies under this Agreement are cumulative and not exclusive of any other rights, remedies, powers and privileges that may be available under this Agreement or otherwise.

shall be deemed effectively given upon personal delivery to the party to be notified (whether by courier or fax) or one (1) Business Day following timely deposit with a reputable international overnight courier with overnight delivery
instructions at the address indicated below or at such other address as such party may designate by ten (10) days’ advance written notice to the other parties pursuant to these provisions.
