	 	2.	Extent of Employment. 

 (a) During the Term of
Employment, the Executive shall perform his obligations hereunder faithfully and to the best of his ability under the direction of the Chief Operating Officer to which the Executive shall directly report, and shall abide by the rules, customs and
usages from time to time established by the Company or Holdings. 

 (b) During the Term of Employment, the Executive shall devote all of his business time, energy and skill
to the performance of his duties, responsibilities and obligations hereunder (except for vacation periods and reasonable periods of illness or other incapacity), consistent with past practices and norms in similar positions. The Executive will have
such authority and power as are inherent to the undertakings applicable to his position as Chief Financial Officer and which are necessary to carry out his responsibilities and the duties required of him hereunder. 
 (c) Nothing contained herein shall require Executive to follow any directive or to perform any act which would violate any laws, ordinances, regulations
or rules of any governmental, regulatory or administrative body, agent or authority, any court or judicial authority, or any public, private or industry regulatory authority (collectively, “Regulations”). Executive will not
(i) breach or violate any provision of any Regulations in any material respect or (ii) otherwise act in any manner which might reasonably be expected to have a material adverse effect on the ongoing business, operations, conditions,
prospects or other business relationships or properties of any company in the Company Group or Holdings. 
  

	 	3.	Compensation. 

 (a) Base Salary. During the
Term of Employment, the Company shall pay compensation to Executive as base compensation for his services hereunder, in substantially equal bi-weekly installments, an annual base salary of $295,000 (the “Base Salary”). The Board of
Directors of Holdings (the “Board of Directors”) shall annually, and based on the recommendation of the Chief Operating Officer, determine whether the Base Salary should be increased and, if so, the amount of such increase.

 (a) Company Termination.
Subject to the Company’s obligations to make the payments contemplated by Section 4(d), the Term of Employment may be terminated at any time by the Company: 
 (i) upon the death of Executive; 
 (ii) in the event that because of physical or mental disability the Executive is unable to perform, and does not perform, as certified by a mutually agreeable competent medical physician, his material duties hereunder
for 180 days in any continuous 210 day period; 
 (iii) for Cause or Material Breach; or 
  

 2 

 (iv) for any other reason not referred to in clauses (i) through
(iii) including nonrenewal of the Term by the Company under Section 1 or no reason, and the Company shall not be required to specify a reason for the termination, provided that termination of the Executive’s employment by the
Company shall be deemed to have occurred under this clause (iv) only if it is not for reasons described in clauses (i) through (iii) such that this Agreement, subject to the provisions of Section 4(d), shall be construed
as terminable at will by the Company. 
 Executive acknowledges that no representations or promises have been made concerning the grounds for
termination or the future operation of the Company’s business, and that, except as set forth in the following sentence, nothing contained herein or otherwise stated by or on behalf of the Company modifies or amends the right of the Company to
terminate Executive at any time, with or without Cause or for Material Breach. Termination shall become effective 30 days after written notice, or, if for Cause or Material Breach, upon the delivery by the Company to the Executive of written
notice specifying the basis of such termination and, if for Cause or Material Breach, the specific reasons therefore.

either Executive or the Company (a “Voluntary Termination”), after 30 days’ prior written notice to the Company and its Board of Directors, provided, that the expiration of the Term of Employment pursuant to
Section 1, or any renewal term thereof, will not be considered a Voluntary Termination. 
 (c) Mutual Termination. Subject
to the Company’s obligations to make the payments contemplated by Section 4(d), the Term of Employment may be terminated at any time by the mutual agreement of the Company and the Executive. Any termination of the Executive’s
employment by mutual agreement of the parties will be memorialized by an agreement which is reduced to writing and signed by the Executive and a duly appointed officer of the Company.

of Employment. In the event Executive’s employment is terminated pursuant to: 
 (i) Sections 4(a)(i) [Death] or

termination; and 
 (iii) Section 4(a)(iv) [Any or No Reason] by the Company or Section 4(b)(iii)
[Material Reduction & Relocation] by the Executive, will pay to Executive the Executive’s base salary through December 31, 2009, the balance of the term of the original Agreement, or for a 12 month period, whichever is longer;
provided, however, if the termination of employment occurs after a Change of Control such payment will be through December 31, 2009, the balance of the term of the original Agreement, or for a 24 month period, whichever is longer.

 (e) Continuing Provisions. Termination of the Term of Employment will not terminate Sections 7, 8, 9,
10, 12 through 24, and related definitions, or any other provisions not associated specifically with the Term of Employment. 
 (f) Mitigation. In the event of termination, the Executive shall not have a duty to mitigate the Company’s payment obligations under Section 4(d) by seeking alternative employment; provided, however,

notice by the Company or the Executive, as the case may be, indicating that the Term of Employment is to be terminated, and ending on the actual date the Term of Employment is terminated, which, in any event, shall be no later than 90 days
following the delivery of such notice, the Executive shall continue to perform his duties as set forth in this Agreement, and shall also perform such services for the Company as are necessary and appropriate for a smooth transition to the

discretion of the Board of Directors, from time to time to other members of senior management.

Period”), the Executive shall not, subject to this Section 7, without the express written approval of the Board of Directors of the Company, directly or indirectly, in one or a series of transactions, own, manage, operate,
control, invest or acquire an interest in, whether as a proprietor, partner, stockholder, member, lender, director, officer, employee, joint venturer, investor, lessor, supplier, customer, agent, representative or other participant, or otherwise
engage or participate in, whether as a proprietor, partner, stockholder, member, lender, director, officer, employee, joint venturer, investor, lessor, supplier, customer, agent, representative or other participant, any business which competes,
directly or indirectly, with the Business in the Market (“Competitive Business”) without regard 

  

 5 

 
to (A) whether the Competitive Business has its office, manufacturing or other business facilities within or without the Market, (B) whether any of
the activities of the Executive occur or are performed within or without the Market or (C) whether the Executive resides, or reports to an office, within or without the Market; provided, however, that (x) the Executive may,
anywhere in the Market, directly or indirectly, in one or a series of transactions, own, invest or acquire an interest in up to two percent (2%) of the capital stock of a corporation whose capital stock is traded publicly, or that (y) the
Executive may accept employment with a successor company to the Company. 
 (b) Non-Solicitation. If the Executive’s employment
is terminated, then, subject to this Section 7, the Executive shall not during the Restricted Period, without the Company’s prior written consent, (A) directly or indirectly, in one or a series of transactions, recruit, solicit
or otherwise induce or influence any proprietor, partner, stockholder, member, lender, director, officer, employee, sales agent, joint venturer, investor, lessor, customer, supplier, agent, representative or any other person which has a business
relationship with the Company Group or had a business relationship with the Company Group within the twenty-four (24) month period preceding the date of the incident in question, to discontinue, reduce or modify such employment, agency or
business relationship with the Company Group, or (B) employ or seek to employ or cause any Competitive Business to employ or seek to employ any person or agent who is then (or was at any time within twelve (12) months prior to the date the

employee with respect to a future employment opportunity. 
 (c) Non-Disclosure. The Executive further agrees, during and after the
Term of Employment, the Restricted Period and thereafter, that the Executive will not, directly or indirectly in one or a series of transactions disclose to any person or use or otherwise exploit for his own benefit or for the benefit of anyone

Company Group who need to know such Confidential Information in order to perform the services or conduct the operations required or expected of them in the Business. The Executive shall use his best efforts to prevent the removal of any Confidential
Information from the premises of the Company Group, except as required in his normal course of employment by the Company Group. During the Term, the Executive shall use his commercially reasonable efforts to cause all persons or entities to whom
Confidential Information shall be disclosed by the Executive hereunder to observe the terms and conditions set forth herein as though each such person or entity was bound hereby. After the Term, the Executive shall not disclose Confidential
Information other than to his advisors, representatives and agents who execute a confidentiality agreement whereby they will agree to observe the confidentiality terms and conditions set forth herein. The Executive shall have no obligation hereunder
to keep confidential any Confidential Information if and to the extent disclosure of any thereof is specifically required by law; provided, however, that in the event disclosure is required by applicable law, the Executive shall
provide the Company with prompt notice of such requirement to the extent allowed by law, prior to making any disclosure, so that the Company may seek an appropriate protective order. At the request of the Company, the Executive agrees to deliver to
the Company all Confidential 

  

 6 

 
Information which the Executive may possess or control. The Executive agrees that all Confidential Information of the Company Group (whether now or hereafter
existing) conceived, discovered or made by him during his employment with the Company Group exclusively belongs to the Company Group (and not to the Executive). The Executive will promptly disclose such Confidential Information to the Company Group
and perform all actions reasonably requested by the Company Group to establish and confirm such exclusive ownership. As used herein, the term “Confidential Information” means any confidential information including, without
limitation, any study, data, calculations, software storage media or other compilation of information, patent, patent application, copyright, trademark, trade name, service mark, service name, “know-how”, trade secrets, customer lists,

whether or not registered, and including all files, records, manuals, books, catalogues, memoranda, notes, summaries, plans, reports, records, documents and other evidence thereof. The term Confidential Information does not include, and there shall
be no obligation hereunder with respect to, information that becomes generally available to the public other than as a result of a disclosure by such shareholder not permissible hereunder. 
 (d) Non-Disparagement. The Executive agrees, during and after the Term of Employment, the Restricted Period and thereafter, that he shall not make
any false, defamatory or disparaging statements about Holdings or the Company Group or the officers or directors of Holdings or the Company Group. During and after the Executive’s employment with the Company Group, the Company agrees on behalf
of itself and its subsidiaries that neither the officers nor the directors of the Company Group shall make any false, defamatory or disparaging statements about the Executive. 
 (e) Specific Performance. All the parties hereto agree that their rights under this Section 7 are special and unique and that
violation thereof would not be adequately compensated by money damages and each grants the other the right to specifically enforce (including injunctive relief where appropriate) the terms of this Agreement. 
  

	 	8.	Defense of Claims. 

 The Executive agrees that, for
the period beginning on the date hereof, and continuing for a reasonable period after termination or expiration of the Term of Employment, the Executive will cooperate with the Company in defense of any claims that may be made against the Company
Group, and will cooperate with the Company in the prosecution of any claims that may be made by Company Group, to the extent that such claims may relate to services performed by the Executive for the Company Group. The Executive agrees to promptly
inform the Company if he becomes aware of any lawsuits involving such claims that may be filed against Holdings or the Company Group. The Company agrees to reimburse the Executive for all of the Executive’s reasonable out-of-pocket expenses
associated with such cooperation, including travel expenses. For periods during and following the Executive’s employment with the Company, the Company agrees to provide reasonable compensation to the Executive for such cooperation in addition

	 	16.	Waiver of Breach; Specific Performance. 

 The waiver
by the Company or Executive of a breach of any provision of this Agreement by the other party shall not operate or be construed as a waiver of any other breach of such other party. Each of the parties (and third party beneficiaries) to this
Agreement will be entitled to enforce its rights under this breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that the Company would be irreparably injured by a
violation of Sections 7 or 8 of this Agreement, that the provisions of such sections are reasonable and that the Company could not adequately be compensated in monetary damages, in light of the sensitivity of the non-public
information of the Company to which the Executive will be exposed and that any party (and third party beneficiaries) may in its sole discretion apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive
relief, including temporary restraining orders, preliminary injunctions and permanent injunctions in order to enforce or prevent any violations of the provisions of such sections of this Agreement. 
  

	 	17.	Assignment; Third Parties. 

 Neither the Executive
nor the Company may assign, transfer, pledge, hypothecate, encumber or otherwise dispose of this Agreement or any of his or its respective rights or obligations hereunder, without the prior written consent of the other. The parties agree and
acknowledge that each of Holdings, its direct and indirect subsidiaries and the shareholders of, lenders to and investors therein are intended to be third party beneficiaries of, and have rights and interests in respect of, Executive’s
agreements set forth in Sections 7 and 8. 
  

	 	18.	Amendment; Entire Agreement. 

 This Agreement may
not be changed orally but only by an agreement in writing agreed to by the party against whom enforcement of any waiver, change, modification, extension or discharge is sought. This Agreement, the Shareholders Agreement and the Restricted Stock
Agreement constitute the entire agreement between the parties concerning the subject matter hereof and supersedes all prior and contemporaneous agreements, if any, between the parties relating to the subject matter hereof. The enforceability of this
Agreement shall not cease or otherwise be adversely affected by the termination of the Executive’s employment with the Company. The Executive and the Company agree that the language used in this Agreement is the language chosen by the parties
to express their mutual intent, and that no rule of strict construction is to be applied against any party hereto. 
  

	 	19.	Arbitration. 

 (a) Except with respect to disputes
or controversies arising out of Sections 7 or 8 hereto, any dispute between any of the parties hereto or claim by a party against another party arising out of or in relation to this Agreement or in relation to any alleged breach
thereof shall be finally determined by arbitration in accordance with the rules then in force by the American Arbitration Association. The arbitration proceedings shall take place in Wilmington, Delaware, 

  

 13 

 
or such other location as the parties in dispute hereafter may agree upon; and such proceedings shall be governed by the laws of the State of Delaware as
such laws are applied to agreements between residents of such State entered into and to be performed entirely within that State. 
 (b) The
parties shall agree upon one arbitrator, who shall be an individual skilled in the legal and business aspects of the subject matter of this Agreement and of the dispute. If the parties cannot agree upon one arbitrator, each party in dispute shall
select one arbitrator and the arbitrators so selected shall select a third arbitrator. In the event the arbitrators cannot agree upon the selection of the third arbitrator, the third arbitrator shall be appointed by the American Arbitration
Association at the request of any of the parties in dispute. The arbitrators shall, if possible, be individuals skilled in the legal and business aspects of the subject matter of this Agreement and of the dispute. 
 (c) The decision rendered by the arbitrator or arbitrators shall be accompanied by a written opinion in support thereof. The decision shall be final and
binding upon the parties in dispute without right of appeal. Judgment upon the decision may be entered into any court having jurisdiction thereof, or application may be made to that court for a judicial acceptance of the decision and any other
enforcement. 
 (d) THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED, APPLIED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
DELAWARE. EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT IN THE EVENT OF ANY BREACH OF THIS AGREEMENT, THE NON-BREACHING PARTY WOULD BE IRREPARABLY HARMED AND COULD NOT BE MADE WHOLE BY MONETARY DAMAGES, AND THAT, IN ADDITION TO ANY OTHER
REMEDY TO WHICH THEY MAY BE ENTITLED AT LAW OR IN EQUITY, THE PARTIES SHALL BE ENTITLED TO SUCH EQUITABLE OR INJUNCTIVE RELIEF AS MAY BE APPROPRIATE. THE CHOICE OF FORUM SET FORTH IN THIS SECTION 19 SHALL NOT BE DEEMED TO PRECLUDE THE
ENFORCEMENT OF ANY JUDGMENT OF A DELAWARE FEDERAL OR STATE COURT OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SUCH A JUDGMENT IN ANY OTHER APPROPRIATE JURISDICTION.

status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving NexGen, each of the other Parties will cooperate with him or it and his or its counsel in the
contest or defense, make available their personnel, and provide such testimony and access to their books and records as shall be necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending
Party (unless the contesting or defending Party is entitled to indemnification therefore under §7 below). 
 (c) Confidentiality.
Each of the Sellers will treat and hold as such all of the Confidential Information, refrain from using any of the Confidential Information except in connection with this Agreement, and deliver promptly to the Buyer or destroy, at the request and
option of the Buyer, all tangible embodiments (and all copies) of the Confidential Information which are in his possession. In the event that any of the Sellers is requested or required (by oral question or request for information or documents in
any legal proceeding, interrogatory, subpoena, civil investigative demand, or similar process) to disclose any Confidential Information, that Seller will notify the Buyer promptly of the request or requirement so that the Buyer may seek an
appropriate protective order or waive compliance with the provisions of this §6(c). If, in the absence of a protective order or the receipt of a waiver hereunder, any of the Sellers is, on the advice of counsel, compelled to disclose any
Confidential Information to any tribunal or else stand liable for contempt, that Seller may disclose the Confidential Information to the tribunal; provided, however, that the disclosing Seller shall use his reasonable best efforts to
obtain, at the reasonable request and expense of the Buyer, an order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as the Buyer shall designate. The foregoing
provisions shall not apply to any Confidential Information which is generally available to the public immediately prior to the time of disclosure. 
 6. Deliverables at Closing. 
 (a) The Sellers shall deliver to the Buyer: 
 (i) the resignations, effective as of the Closing, of each manager of NexGen; 
 (ii) Annex I and the Disclosure Schedules of §4; 
 (iii) all of their 80.1 Units of NexGen Units; and 
 (iv) the Amendments to the Noncompetition Agreement signed by Hashem Akhavan-Tafti, A. Paul Schaap, and Gary T. Priestap, each in form and
substance reasonably acceptable to Buyer and the applicable Individual Seller. 
 (b) The Buyer shall deliver to the Sellers: $36,045,000 by
delivery of cash payable by wire transfer to the account set forth opposite the respective Seller’s name on Appendix I or delivery of other immediately available funds.

 7. Remedies for Breaches of This Agreement. 
 (a) Survival of Representations and Warranties. All of the SOL Representations of the Parties shall survive the Closing hereunder forever
thereafter (subject only to the applicable statute of limitations). All of the other representations and warranties of the Parties contained in this Agreement shall survive the Closing and continue in full force and effect for one year thereafter.

 (b) Indemnification Provisions for Benefit of the Buyer. 
 (i) In the event any of the Sellers breaches (or in the event any third party alleges facts that, if true, would mean any of the
Individual Sellers has breached) any of their representations, warranties, and covenants contained herein, and, if there is an applicable survival period pursuant to §7(a) above, provided that the Buyer makes a written claim for indemnification
against any of the Individual Sellers pursuant to §9(h) below within such survival period, then, subject to the terms of this Section 7, the Sellers agree to indemnify the Buyer from and against any Adverse Consequences the Buyer
may suffer through and after the date of the claim for indemnification (including any Adverse Consequences the Buyer may suffer after the end of any applicable survival period) resulting from, arising out of, relating to, in the nature of, or caused
by the breach (or the alleged breach). 
 (ii) Subject to the terms of this Section 7, the Sellers agree to
indemnify the Buyer from and against any Adverse Consequences the Buyer may suffer resulting from, arising out of, relating to, in the nature of, or caused by any Liability of NexGen (x) for any Taxes of NexGen with respect to any Tax year or
portion thereof ending on or before the Closing Date (or for any Tax year beginning before and ending after the Closing Date to the extent allocable to the portion of such period beginning before and ending on the Closing Date), to the extent such
Taxes are not reflected in the reserve for Tax Liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) shown on the Financial Statements. 
 (c) Indemnification Provisions for Benefit of the Sellers. In the event the Buyer breaches (or in the event any third party alleges facts that, if
true, would mean the Buyer has breached) any of its representations, warranties, and covenants contained herein, and, if there is an applicable survival period pursuant to §7(a) above, provided that any of the Sellers makes a written claim for
indemnification against the Buyer pursuant to §9(h) below within such survival period, then the Buyer agrees to indemnify each of the Sellers from and against any Adverse Consequences the Individual Seller may suffer through and after the date
of the claim for indemnification (including any Adverse Consequences the Individual Seller may suffer after the end of any applicable survival period) resulting from, arising out of, relating to, in the nature of, or caused by the breach (or the
alleged breach). 
 (d) Determination of Adverse Consequences. The Parties shall take into account the time cost of money (using its
or their cost to borrow money from its usual and customary lenders as the discount rate) in determining Adverse Consequences for purposes of this §7. All indemnification payments under this §7 shall be deemed adjustments to the Purchase
Price. 
 (e) Other Indemnification Provisions. Each of the Individual Sellers hereby agrees that he or it will not make any claim for
indemnification against NexGen by reason of the fact that he was a manager, officer, employee, or agent of NexGen. 
 (f) Limitations on
Indemnity. The parties expressly intend and agree as follows (the limitations and qualifications contained in this Section 7(f) being a material inducement to Sellers and Buyer in agreeing to execute and deliver this Agreement and to
consummate the transactions contemplated by this Agreement): 
 (i) Sellers shall have no obligation to indemnify Buyer in
respect of Adverse Consequences pursuant to Section 7(b) unless: 
 (A) such Adverse Consequences exceed
$1,000,000 in the aggregate (the “Indemnification Threshold”), and then only to the extent such Adverse Consequences exceed the Indemnification Threshold; provided, however, the Indemnification Threshold limitation shall not apply
in any manner whatsoever to any breach of the SOL Representations. 
  

 9 

 (ii) Buyer shall have no obligation to indemnify Sellers in respect of Adverse
Consequences pursuant to Section 7(c) unless such Adverse Consequences exceed the Indemnification Threshold, and then only to the extent such Adverse Consequences exceed the Indemnification Threshold; provided, however, the
Indemnification Threshold limitation shall not apply in any manner whatsoever to any breach of the SOL Representations. 
 (iii) Except as provided below, the aggregate amount of Adverse Consequences that may be recovered by the Buyer under Section 7(b) may not exceed (i) with respect to the Sellers collectively, an aggregate of $3,600,000 (the
“Buyer Cap”) and (ii) with respect to each particular Seller, such Seller’s pro rata portion of the Buyer Cap based upon his or its Applicable Percentage. The aggregate amount of Adverse Consequences that may be recovered
by the Sellers under Section 7(c) may not exceed $3,600,000 (the “Seller Cap”). Neither the Buyer Cap nor the Seller Cap shall apply to the obligations of any Party hereto to the extent a breach results from fraud or
intentional misrepresentation by such Party. 
 (iv) The Sellers shall not have any claim for contribution from or against
NexGen as a result of any indemnification or other payments made by any of the Sellers to the Buyer pursuant to this Agreement. 
 (v) The amount of any Adverse Consequences for which indemnification is provided under this Agreement shall be net of any amounts actually recovered by the indemnified party or its Affiliates with respect to such Adverse Consequences under
insurance policies maintained by NexGen prior to the date hereof, net of reasonable expenses incurred by the indemnified party in obtaining such recovery. Buyer will (and will cause NexGen to) use its commercially reasonably efforts to seek full
recovery under the insurance policies referenced in the foregoing sentence; provided, however, that the indemnified party shall have no obligation to first submit or to collect upon any applicable insurance coverage as a precondition
to making a claim for indemnification hereunder or obtaining indemnification for Adverse Consequences therefor, and the Parties hereto agree, without limiting any other rights any indemnifying party may have against Buyer, not to delay in any manner
the payment to Buyer of such indemnification based on Buyer’s non-fulfillment of the foregoing obligation at the time any such claim is made. If permitted under the terms of the applicable insurance policies, in lieu of the foregoing, the
indemnified party may subrogate or assign its rights to recover under such insurance policies to the Sellers. 
 (vi) After
the Closing, the remedies provided in this Section 7 are the sole and exclusive remedies available to a Party for any and all Adverse Consequences resulting from any breach or violation of this Agreement by another Party, except for the
remedies of specific performance, injunction and other equitable relief; provided, however, that (i) Buyer shall not be deemed to have waived any rights, claims, causes of action or remedies if and to the extent such rights,
claims, causes of action or remedies may not be waived under applicable law or in instances of fraud, intentional misrepresentation or intentional breach and (ii) none of the Sellers shall be deemed to have waived any rights, claims, causes of
action or remedies if and to the extent such rights, claims, causes of action or remedies may not be waived under applicable law or in instances of fraud, intentional misrepresentation or intentional breach. 
 (vii) Notwithstanding any other provision of this Agreement, the Sellers shall not indemnify, defend or hold harmless Buyer or any of its
Affiliates (including NexGen) or any transferee of Buyer or any of its Affiliates, from any liability for Taxes attributable to any action taken on the Closing Date after the Closing by Buyer or any of its Affiliates (including NexGen) or any
transferee of Buyer or any of its Affiliates, that is allocable to the day following the Closing Date by Treasury Regulation 1.1502-76(b)(1)(ii)(B). 
  

 10 

 8. Tax Matters. The following provisions shall govern the allocation of responsibility as between
Buyer and Sellers for certain tax matters following the Closing Date: 
 (a) Tax Periods Ending on or Before the Closing Date. Buyer
shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for NexGen for all periods beginning prior to the Closing Date and ending on or after the Closing Date which are filed after the Closing Date. Buyer shall permit the
Sellers to review and comment on such Tax Return described in the preceding sentence prior to filing. The Sellers shall reimburse Buyer for Taxes of NexGen paid with respect to periods prior to the Closing Date to the extent such Taxes are not
reflected in the reserve for Tax Liability shown on the Financial Statements. For purposes of this Section, the portion of such Tax which relates to the portion of such Taxable period ending on the Closing Date shall be deemed to be the amount of
such Tax for the entire Taxable period multiplied by a fraction the numerator of which is the number of days in the Taxable period ending on the Closing Date and the denominator of which is the number of days in the entire Taxable period.

 (b) Certain Taxes and Fees. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance
fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid by Sellers when due, and Sellers will, at their own
expense, file all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges, and, if required by applicable law, Buyer will, and will cause its Affiliates to, join in the execution of any such Tax Returns and
other documentation. 
 9. Miscellaneous. 
 (a) Waiver of LLC Agreement Provisions. NexGen and each of the Sellers hereby waive any rights of first refusal, rights of first offer, options to purchase or any other rights that they, or any of them, may
have to purchase or otherwise acquire the NexGen Units under the LLC Agreement, statute or otherwise and expressly agree that notwithstanding any provision of the LLC Agreement or statute to the contrary, NexGen shall not be dissolved and wind up
but shall continue without interruption after the Closing with Buyer as the sole Member (as defined in the LLC Agreement). To the extent any provision or provisions of the LLC Agreement are inconsistent with the provisions of this Agreement and the
consummation of the transactions contemplated hereby, the parties hereto agree that the inconsistent provisions of the LLC Agreement shall be deemed modified, waived or approved as required to make the consummation of the transactions contemplated
hereby allowable under and consistent with the LLC Agreement. 
 (b) Press Releases and Public Announcements. No Party shall issue any
press release or make any public announcement relating to the subject matter of this Agreement without the prior written approval of the Buyer and the Individual Sellers; provided, however, that any Party may make any public disclosure
it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party will use its reasonable efforts to advise the other Parties prior to making the
disclosure). 
 (c) No Third-Party Beneficiaries. This Agreement shall not confer any rights or remedies upon any Person other than
the Parties and their respective successors and permitted assigns. 
 (d) Entire Agreement. This Agreement (including the documents
referred to herein) constitutes the entire agreement among the Parties and supersedes any prior understandings, agreements, or representations by or among the Parties, written or oral, to the extent they related in any way to the subject matter
hereof. 
  

 11 

 (e) Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of
the Parties named herein and their respective successors and permitted assigns. No Party may assign either this Agreement or any of his or its rights, interests, or obligations hereunder without the prior written approval of the Buyer and the
Requisite Sellers; provided, however, that the Buyer may (i) assign any or all of its rights and interests hereunder to one or more of its Affiliates and (ii) designate one or more of its Affiliates to perform its obligations
hereunder (in any or all of which cases the Buyer nonetheless shall remain responsible for the performance of all of its obligations hereunder). 
 (f) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which together will constitute one and the same instrument. 
 (g) Headings. The section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement. 
 (h) Notices. All notices, requests, demands, claims, and other communications hereunder will be
in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given if (and then two business days after) it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to

   Attention General Counsel 
 Any Party may send any notice, request, demand, claim, or other communication hereunder to the intended recipient at the address set forth above using any other means (including personal delivery, expedited courier, messenger service,
telecopy, ordinary mail, or electronic mail), but no such notice, request, demand, claim, or other communication shall be deemed to have been duly given unless and until it actually is received by the intended recipient. Any Party may change the
address to which notices, requests, demands, claims, and other communications hereunder are to be delivered by giving the other Parties notice in the manner herein set forth. 
 (i) Governing Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Michigan without
giving effect to any choice or conflict of law provision or rule (whether of the State of Michigan or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Michigan.  
 (j) Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the
Buyer and the Sellers. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of
warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 
 (k)
Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall 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. 
 (l) Expenses. Each of the
Buyers, the Sellers, and NexGen will bear his or its own costs and expenses (including legal fees and expenses) incurred in connection with this Agreement and the transactions contemplated hereby. 
 (m) 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 shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of
this Agreement. Any reference to any federal, state, local, or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The word “including” shall mean
including without limitation. The Parties intend that each representation, warranty, and covenant contained herein shall have independent significance. If any Party has breached any representation, warranty, or covenant contained herein in any
respect, 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 shall not detract from or mitigate the fact
that the Party is in breach of the first representation, warranty, or covenant. 
  

 13 

 (n) Incorporation of Exhibits, Annexes, and Schedules. The Exhibits, Annexes, and Schedules
identified in this Agreement are incorporated herein by reference and made a part hereof. 
 (o) Submission to Jurisdiction. Each of
the Parties submits to the jurisdiction of any state or federal court sitting in Oakland County, Michigan, in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may
be heard and determined in any such court. Each Party also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the Parties waives any defense of inconvenient forum to the maintenance
of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto. 
 (p) Disclosure Schedules. 
 (i) Notwithstanding anything to the contrary contained in
this Agreement or otherwise, all disclosures set forth in the Disclosure Schedules to this Agreement shall qualify each and every representation and warranty of Sellers notwithstanding that any disclosure in the Disclosure Schedules is made with
reference to a particular section of this Agreement and notwithstanding that a particular representation or warranty may refer to a different Disclosure Schedule or may not make any reference to any Disclosure Schedules. 
 (ii) Certain information in the Disclosure Schedules may not be required to be disclosed pursuant to this Agreement. Any such information
is included solely for informational purposes, and the inclusion of such information shall not be deemed to enlarge or enhance any of the representations or warranties of Sellers in this Agreement or otherwise alter in any way the terms of this
Agreement. 
 (iii) Neither the specification of any dollar amount in any representation, warranty, or covenant contained in
this Agreement nor the inclusion of any specific item in the Disclosure Schedules is intended to imply that such amount, or higher or lower amounts, or the item so included or other items, are or are not material, and no Party shall use the fact of
the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between the Parties as to whether any obligation, item, or matter not described herein or included in the Disclosure Schedules is or is not material
for purposes of this Agreement. Further, neither the specification of any item or matter in any representation, warranty, or covenant contained in this Agreement nor the inclusion of any specific item in the Disclosure Schedules is intended to imply
that such item or matter, or other items or matters, are or are not in the Ordinary Course of Business, and no Party shall use the fact of setting forth or the inclusion of any such items or matter in any dispute or controversy between the Parties
as to whether any obligation, item, or matter not described herein or included in the Disclosure Schedules is or is not in the Ordinary Course of Business for purposes of this Agreement. 
 (q) Attorney-Client Privilege and Conflict Waiver. Miller, Canfield, Paddock and Stone, P.L.C. has represented both the NexGen and the Individual
Sellers in connection with this Agreement and the transactions and other documents contemplated hereby. All of the Parties recognize the community of interest that exists and will continue to exist until the Closing between NexGen on the one hand
and the Individual Sellers on the other, and the parties agree that such community of interest should continue to be recognized after the Closing. Specifically, the parties agree that: 
 (i) Neither NexGen nor any Seller will seek to have Miller, Canfield, Paddock and Stone, P.L.C. disqualified from representing any
Individual Seller or any affiliate of an Individual Seller in connection with any dispute that may arise between any Individual Seller or affiliate of an Individual Seller and Buyer in connection with this Agreement or any of the transactions or
other documents contemplated hereby. 
  

 14 

 (ii) In connection with any dispute that may arise between any Individual Seller or
affiliate of an Individual Seller and Buyer or NexGen, the Individual Seller or affiliate of an Individual Seller involved in such dispute (and not NexGen or any of the members of NexGen) will have the right to decide whether or not to waive any
attorney client privilege that may apply to any communications between NexGen and Miller, Canfield, Paddock and Stone, P.L.C. that occurred before the Closing. 
 (r) Limitation on Remedies. Notwithstanding anything in this Agreement to the contrary, Sellers shall not be liable to Buyer for any incidental, consequential, special, or punitive damages of any kind or
nature, including, without limitation, for the breach of the this Agreements, whether such liability is asserted on the basis of contract, tort (including negligence or strict liability), or otherwise, even if Sellers or Buyer have warned or advised
or been warned or advised of the possibility of any such loss or damage.
