jurisdiction of organization and (b) has all requisite power, and has all material governmental licenses, authorizations, consents and approvals, necessary to own its properties and carry on its business as now being conducted, except where the

Transaction Documents to which it is or will be party, and to carry out its obligations thereunder. The execution and delivery of the Transaction Documents and the performance of each Seller’s obligations thereunder have been duly authorized by

 -3-









 
is or will be a party has been (in the case of this Agreement and the Transaction Documents executed on the date hereof), or will be at the Closing (in the case of any other Transaction
Documents), duly executed and delivered by such Seller and constitutes, or will constitute at the Closing, as applicable, such Seller’s valid and binding obligation, enforceable against such Seller in accordance with its terms (except to the
extent that its enforceability may be limited by the Remedies Exception). 
 Section 3.03 Consents and Approvals. No
consent, approval, waiver or authorization of, or filing, registration or qualification with any Governmental Authority or any other Person is required on the part of any Seller for such Seller to execute and deliver the Transaction Documents to

clarification, the Parties acknowledge that the Sellers are not making any representation and warranty in this Section 3.03 with respect to any Contract to which a Seller is not, but an Acquired Company is, a party.

will be a party, and compliance by each Seller with the terms and provisions thereof, do not and will not (a) violate any provision of any Law applicable to (i) such Seller, AMV or the General Partner or any of their respective properties

right, remedy or benefit, including any right of offer, refusal, termination, cancellation or acceleration, under any Contract to which any Seller, AMV or the General Partner is a party or by which any Seller, AMV, the General Partner or any of
their respective properties may be bound or receives any material right or benefit. For the avoidance of doubt, this Section 3.04 shall not cover Contracts to which the General Partner is a party or is bound solely on behalf of another
Acquired Company or properties of any Acquired Company not otherwise held or owned directly by the General Partner.

a “Tribunal”)) to disclose any Confidential Information, such Party shall, if legally permissible, (i) promptly notify the other Party of the existence and terms of such request, (ii) consult with such other Party
as to the advisability of taking legally available steps to resist or narrow such request and (iii) assist such other Party, at such other Party’s expense, in seeking a protective order or other appropriate remedy. The Party (or its

 (a) From and after the Closing, subject to Section 8.01 and Section 8.04, the Sellers, jointly and severally, hereby agree to indemnify and hold the Buyer and each of its current
and future Affiliates (excluding any Person that is or becomes an Affiliate of the Buyer solely as a result of the purchase of publicly traded securities from the general public) and each of the respective indirect and direct equity holders,
members, directors, managers, officers, employees and agents of the foregoing (collectively, the “Buyer Indemnified Parties”) harmless from and against, and pay to the applicable Buyer Indemnified Parties the amount of, any
and all losses, liabilities, claims, obligations, deficiencies, demands, judgments, settlements, damages, interest, fines, penalties, claims, suits, actions, causes of action, assessments, awards, Taxes, costs and expenses (including costs of
investigation and defense and attorneys’ and other professionals’ fees), whether or not involving a Third Party Claim (a “Loss”) based upon, attributable to or resulting from (including any and all Proceedings,
demands, or assessments arising out of): 
 (i) any inaccuracy, untruth or breach of the representations or warranties made by
the Sellers in this Agreement and in any certificate delivered pursuant hereto; and 
 (ii) any breach of any covenant or other
agreement on the part of the Sellers under this Agreement and in any certificate delivered pursuant hereto. 
 (b) From and
after the Closing, subject to Section 8.01 and Section 8.04, the Buyer hereby agrees to indemnify and hold the Sellers and their respective Affiliates and each of the members, directors, managers, officers, employees and
agents of the foregoing (collectively, the “Seller Indemnified Parties”) harmless from and against, and pay to the applicable Seller Indemnified Parties the amount of, any and all Losses based upon, attributable to or
resulting from (including any and all Proceedings, demands, or assessments arising out of): 

  
 -24-









 (i) any inaccuracy, untruth or breach of the representations or warranties made by the
Buyer in this Agreement and any certificate delivered pursuant hereto; and 
 (ii) any breach of any covenant or other
agreement on the part of the Buyer under this Agreement and in any certificate delivered pursuant hereto. 
 (c) Materiality,
Seller Material Adverse Effect, Company Material Adverse Effect, Buyer Material Adverse Effect and similar qualifiers contained in any representation or warranty, or in any defined term used therein, shall be disregarded for purposes of subsections
(a)(i) and (b)(i) of this Section 8.02 in (i) determining any inaccuracy, untruth or breach of the representations or warranties contained herein and (ii) calculating the amount of Losses suffered by an
Indemnified Party. 
 Section 8.03 Indemnification Procedure.  

(a) Each Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant
to Section 8.02, such Indemnified Party will assert its claim for indemnification under Section 8.02 (each, a “Claim”) by providing a written notice (a “Claim Notice”) within
the applicable Survival Period to the applicable indemnifying party (the “Indemnifying Party”) specifying, in reasonable detail, to the extent known by such Indemnified Party, the nature and basis for such Claim (e.g., the
underlying representation, warranty or covenant alleged to have been breached and the condition or conduct allegedly resulting in such breach). Notwithstanding the foregoing, an Indemnified Party’s delay in sending a Claim Notice will not
relieve the Indemnifying Party from Liability hereunder with respect to such Claim except to the extent (and limited solely to the extent) of any material prejudice to the Indemnifying Party by such failure or delay, provided that such Claim
Notice is provided within the applicable Survival Period. 
 (b) In the event that any Proceeding is instituted or any Claim is
asserted by any Third Party in respect of which indemnification may be sought under Section 8.02 hereof and in respect of which the Indemnifying Party has agreed in writing to indemnify the Indemnified Party for all of such Indemnified
Party’s Losses (subject to any applicable limitations in this Article VIII) (a “Third Party Claim”), the Indemnifying Party will have the right, at such Indemnifying Party’s expense, to assume the defense of
same including the appointment and selection of counsel on behalf of the Indemnified Party so long as such 

  
 -25-









 
counsel is reasonably acceptable to the Indemnified Party. If the Indemnifying Party elects to assume the defense of any such Third Party Claim, it shall within thirty (30) days notify the
Indemnified Party in writing of its intent to do so. Subject to Section 8.03(c), the Indemnifying Party will have the right to settle or compromise or take any corrective or remedial action with respect to any such Third Party Claim by
all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party. The Indemnified Party will be entitled, at its own cost, to
participate with the Indemnifying Party in the defense of any such Third Party Claim, unless separate representation of the Indemnified Party by counsel is reasonably necessary to avoid a conflict of interest, in which case such representation shall
be at the expense of the Indemnifying Party. If the Indemnifying Party assumes the defense of any such Third Party Claim but fails to diligently prosecute such Third Party Claim, or if the Indemnifying Party does not assume the defense of any such
Third Party Claim, the Indemnified Party may assume control of such defense and in the event the Third Party Claim is determined to be a matter for which the Indemnifying Party is required to provide indemnification under the terms of this
Article VIII, the Indemnifying Party will bear the reasonable costs and expenses of such defense (including fees and expenses of counsel). 
 (c) Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment
or consent decree or permit a default without the Indemnified Party’s prior written consent, in each case, that (i) does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a
binding, irrevocable, written release of any Indemnified Party from all Liability, (ii) provides for any admission of Liability on the part of any Indemnified Party, (iii) requires an admission of guilt or wrongdoing on the part of any
Indemnified Party or (iv) imposes any Liability or continuing obligation on or requires any payment from any Indemnified Party. 
 Section 8.04 Limitations.  
 (a) No Indemnifying Party shall have any
Liability under Section 8.02(a)(i) or Section 8.02(b)(i) related to a representation or warranty other than a Fundamental Representation in respect of any individual claim involving Losses to any Indemnified Party of less
than $100,000 (each, a “De Minimis Claim”), unless such individual claim is directly related to one or more other claims which in the aggregate involve Losses in excess of $100,000, in which case, the Indemnifying Party will
have Liability for the full amount of such claims (subject to the other limitations contained in this Section 8.04) and such claims shall not 

  
 -26-









 
be considered De Minimis Claims (it being understood and agreed that notwithstanding anything in the foregoing to the contrary, solely for the purposes of this Section 8.04(a), all
claims related to any fact or circumstance that causes any representation or warranty made in any particular Section of this Agreement to be inaccurate shall be deemed to be related to all other claims related to such fact or circumstance).

 (b) No Buyer Indemnified Party shall be entitled to indemnification pursuant to Section 8.02(a)(i) related to a
representation or warranty other than a Fundamental Representation unless the aggregate of all Losses claimed by the Buyer Indemnified Parties pursuant to such section that are not De Minimis Claims exceeds 1% of the Purchase Price (the
“Claim Deductible”), in which case, subject to Section 8.04(d), the Sellers shall indemnify the Buyer Indemnified Party only for the Losses in excess of the Claim Deductible. 

(c) No Seller Indemnified Party shall be entitled to indemnification pursuant to Section 8.02(b)(i) related to a
representation or warranty other than a Fundamental Representation unless the aggregate of all Losses claimed by the Seller Indemnified Parties pursuant to such section exceeds the Claim Deductible, in which case, subject to
Section 8.04(d), the Buyer shall indemnify the Seller Indemnified Party only for the Losses in excess of the Claim Deductible. 
 (d) The Sellers shall not have any obligation to indemnify the Buyer Indemnified Parties under Section 8.02(a)(i) for Losses that exceed, in the aggregate, 10% of the Purchase Price;
provided, however, that such limitation shall not apply to Losses of the Buyer Indemnified Parties arising from any Fundamental Representation, and the Sellers’ aggregate Liability for such Losses, together with any other
indemnifiable Losses, shall not exceed the Purchase Price. The Buyer shall not have any obligation to indemnify the Seller Indemnified Parties under Section 8.02(b)(i) for Losses that exceed, in the aggregate, 10% of the Purchase Price;
provided, however, that such limitation shall not apply to Losses of the Seller Indemnified Parties arising from any Fundamental Representation, and the Buyer’s aggregate Liability for such Losses, together with any other
indemnifiable Losses, shall not exceed the Purchase Price. 
 (e) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT,
NEITHER THE BUYER NOR ANY SELLER NOR THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE HEREUNDER TO ANY INDEMNIFIED PARTY FOR ANY (i) PUNITIVE OR EXEMPLARY DAMAGES OR (ii) LOST PROFITS OR CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES EXCEPT, IN THE
CASE OF 

  
 -27-









 
THIS CLAUSE (ii), TO THE EXTENT SUCH LOST PROFITS OR DAMAGES ARE (x) NOT BASED ON ANY SPECIAL CIRCUMSTANCES OF THE PARTY ENTITLED TO INDEMNIFICATION AND (y) THE NATURAL, PROBABLE AND
REASONABLY FORESEEABLE RESULT OF THE EVENT THAT GAVE RISE THERETO OR THE MATTER FOR WHICH INDEMNIFICATION IS SOUGHT HEREUNDER, REGARDLESS OF THE FORM OF ACTION THROUGH WHICH SUCH DAMAGES ARE SOUGHT, EXCEPT IN EACH CASE OF THE FOREGOING CLAUSES
(i) AND (ii), TO THE EXTENT ANY SUCH LOST PROFITS OR DAMAGES ARE INCLUDED IN ANY ACTION BY A THIRD PARTY AGAINST SUCH INDEMNIFIED PARTY FOR WHICH IT IS ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT. 

Section 8.05 Calculation of Losses. In calculating amounts payable to an Indemnified Party, the amount of any indemnified
Losses shall be computed net of (a) payments actually recovered by any Indemnified Party under any insurance policy with respect to such Losses net of expenses and (b) any actual recovery by any Indemnified Party from any Person with
respect to such Losses net of expenses. Each Indemnified Party shall use commercially reasonable efforts to pursue reimbursement for Losses, including under insurance policies and indemnity arrangements. 

Section 8.06 No Duplication. In no event shall any Indemnified Party be entitled to recover any Losses under one Section or
provision of this Agreement to the extent of the full amount of such Losses already recovered by such Indemnified Party, nor shall its insurer or indemnitor be entitled to any kind of subrogation or substitution which would give it the right to make
a claim against the Indemnifying Party. 
 Section 8.07 Tax Treatment of Indemnity Payments. The Sellers and the
Buyer agree to treat any indemnity payment made pursuant to this Article VIII as an adjustment to the Purchase Price for all Tax purposes, unless otherwise required by Law. 

Section 8.08 Exclusive Remedy. 
 (a) EXCEPT (i) PURSUANT TO THIS ARTICLE VIII, SECTION 12.06 OR ANY OTHER TRANSACTION DOCUMENT OR (ii) IN THE CASE OF CRIMINAL ACTIVITY OR FRAUD ON THE PART OF ANY PARTY, BUT
OTHERWISE NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IF THE CLOSING OCCURS, NO PARTY SHALL HAVE ANY LIABILITY, AND NO PARTY SHALL MAKE ANY CLAIM, FOR ANY LOSS (AND THE PARTIES HEREBY WAIVE

ANY RIGHT OF CONTRIBUTION AGAINST EACH OTHER AND THEIR RESPECTIVE AFFILIATES) UNDER, ARISING OUT OF, OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY CERTIFICATE
DELIVERED PURSUANT TO THIS AGREEMENT, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, COMMON LAW, OTHER LAWS OR OTHERWISE. HOWEVER, NOTHING IN THIS SECTION 8.08 SHALL LIMIT THE RIGHTS OF A PARTY TO (i) SEEK AND OBTAIN INJUNCTIVE
RELIEF IN ACCORDANCE WITH SECTION 12.06 OR (ii) PURSUE CLAIMS PURSUANT TO OR ARISING UNDER THE AMV LLC AGREEMENT, THE GENERAL PARTNER LLC AGREEMENT AND THE SELLER GUARANTEE, IN EACH CASE, TO THE EXTENT PROVIDED FOR THEREIN. 

(b) Except as otherwise expressly set forth in this Agreement, any other Transaction Document or in any certificate delivered pursuant
hereto or thereto, each of the Parties, on behalf of itself and its Affiliates, covenants, agrees and acknowledges that (i) no Person other than the express Parties hereto or thereto shall have any obligation or Liability hereunder, under any
Transaction Document or under any certificate delivered pursuant hereto or thereto, and (ii) the Parties and their Affiliates and Representatives shall have no rights of recovery in respect hereof or thereof against, no recourse in respect
hereof or thereof shall be had against, and no personal Liability in respect hereof or thereof shall attach to, any Acquired Company (other than any party to any of the Transaction Documents to the extent of its obligations thereunder to the other
parties thereto or express third party beneficiaries thereof) or any former, current or future Affiliate, general or limited partner, member, equity holder, Representative, director, officer, agent, manager, assignee or employee of any Party, of any
Acquired Company or of any Affiliate of any of the foregoing (other than any party to any of the Transaction Documents to the extent of its obligations thereunder), or any of their respective successors or permitted assignees (excluding any party to
the Transaction Documents to the extent of its obligations thereunder to the other parties thereto or express third party beneficiaries thereof, collectively, “Non-Recourse Persons”), whether by or through attempted piercing
of the “corporate veil”, by or through a claim (whether in tort, contract, at law, in equity or otherwise) by or on behalf of any Party against any Non-Recourse Person, by the enforcement of any judgment, fine or penalty or by any legal or
equitable proceeding, or by virtue of any statute, regulation or other applicable Law, or otherwise. The Non-Recourse Persons shall be express third party beneficiaries of this Section 8.08(b) as if expressly party hereto. 

(c) Notwithstanding Section 8.08(a), nothing contained in this Section 8.08 shall prevent any Party from seeking
and obtaining injunctive relief against the other Party’s activities in breach of this Agreement. 

  
 -29-









 (d) For the avoidance of doubt and notwithstanding anything in the foregoing, nothing in
this Agreement shall limit any claims, remedies or rights of any Party or other Person under the AMV LLC Agreement, the General Partner LLC Agreement and the Seller Guarantee, in each case, to the extent provided for therein. 

Section 8.09 No Reliance. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES MADE IN THIS AGREEMENT, ANY TRANSACTION DOCUMENT OR
IN ANY CERTIFICATE DELIVERED PURSUANT HERETO OR THERETO, NONE OF THE PARTIES OR ANY OTHER PERSON, INCLUDING ANY AFFILIATE OF ANY PARTY, MAKES ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO SUCH PARTIES OR THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT, AND EACH PARTY DISCLAIMS ANY SUCH OTHER REPRESENTATIONS OR WARRANTIES, WHETHER MADE BY SUCH PARTIES OR ANY OF THEIR AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES (INCLUDING WITH RESPECT TO THE
DISTRIBUTION OF, OR ANY SUCH PERSON’S RELIANCE ON, ANY INFORMATION, DISCLOSURE OR OTHER DOCUMENT OR OTHER MATERIAL MADE AVAILABLE IN ANY DATA ROOM, MANAGEMENT PRESENTATION OR IN ANY OTHER FORM IN EXPECTATION OF, OR IN CONNECTION WITH, THE
TRANSACTIONS CONTEMPLATED HEREBY). EXCEPT FOR THE EXPRESS REPRESENTATIONS AND WARRANTIES SET FORTH IN THIS AGREEMENT, ANY TRANSACTION DOCUMENT OR IN ANY CERTIFICATE DELIVERED PURSUANT HERETO OR THERETO, EACH PARTY HEREBY DISCLAIMS ALL LIABILITY AND
RESPONSIBILITY FOR ANY REPRESENTATION, WARRANTY, PROJECTION, FORECAST, STATEMENT, OR INFORMATION MADE, COMMUNICATED, OR FURNISHED (ORALLY OR IN WRITING) TO ANY OTHER PARTY OR ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES

(a) by the mutual written consent of the Sellers and the Buyer; 
 (b) by the Sellers or the Buyer if there shall be in effect a final nonappealable order of a Governmental Authority of competent jurisdiction restraining, enjoining or otherwise prohibiting the
consummation of the transactions contemplated hereby; provided that the right to terminate this Agreement under this Section 10.01(b) shall not be available to any Seller, on the one hand, or the Buyer, on the other hand, if such
order was primarily due to the failure of any of the Sellers, on the one hand, or the Buyer, on the other hand, to perform any of its obligations under this Agreement; 
 (c) by the Buyer if any Seller shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of
any Seller shall have become untrue, in either case such that the conditions set forth in Section 7.02(a) or (b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have
been cured within ten (10) days following receipt by the Sellers of notice of such breach from the Buyer;

perform and comply in all material respects with the covenants and agreements to be performed or complied with by such Party prior to the Closing. 
 Section 10.02 Procedure Upon Termination. In the event of termination of this Agreement by the Buyer or the Sellers, or both, pursuant to Section 10.01, written notice thereof

any Affiliate of such Party that remains an Affiliate at all times following such assignment or in the case of the Sellers, any control person, partner, equity holder, member, stockholder or co-investor of any Seller or its Affiliates and
(b) the Buyer may freely assign this Agreement or any of its rights or obligations hereunder, in whole or from time to time in part to any Person that acquires the Subject Interests (other than pursuant to a registration statement under the

(including legal, accounting, financial advisory and consulting fees and expenses) incurred by such Party in connection with the negotiation and consummation of the transactions contemplated by this Agreement and the other Transaction Documents.

 Section 12.06 Specific Performance. The Parties acknowledge and agree that a breach of this Agreement would cause
irreparable damage to the Buyer and the Sellers and the Buyer and the Sellers will not have an adequate remedy at Law. Therefore, the obligations of the Buyer and the Sellers under this Agreement, including the Sellers’ obligation to sell the
Subject Interests to the Buyer and the Buyer’s obligation to purchase the Subject Interests from the Sellers, shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive
relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any Party may have under this Agreement or otherwise. 

Section 12.07 Entire Agreement. This Agreement (including the Schedules and Exhibits hereto), together with each of the other
Transaction Documents, constitute the entire understanding and agreement between the Parties with respect to the subject matter hereof and supersede any and all prior or contemporaneous discussions, agreements and understandings, whether written or

 Section 12.08 Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision or portion of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law in any jurisdiction by
any applicable Governmental Authority, (a) such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality
or enforceability of any provision in any other jurisdiction, (b) such provision shall be invalid, illegal or unenforceable only to the extent strictly required by such Governmental Authority, (c) to the extent any such provision is deemed
to be invalid, illegal or unenforceable, each of the Sellers and the Buyer agrees that it shall use its best efforts to cause such Governmental Authority to modify such provision so that such provision shall be valid, legal and enforceable as
originally intended to the greatest extent possible and (d) to the extent that the Governmental Authority does not modify such provision, each of the Sellers and the Buyer agrees that they shall endeavor in good faith to exercise or modify such
provision so that such provision shall be valid, legal and enforceable as originally intended to the greatest extent possible. 

Section 12.09 Disclosure Schedules. The inclusion of any information (including dollar amounts) in any section of any
schedule required by this Agreement (the “Disclosure Schedules”) shall not be deemed to be an admission or acknowledgment by the disclosing party or any other Party that such information is required to be listed on such
section of the relevant Disclosure Schedule or is material to or outside the ordinary course of the business of the applicable Person to which such disclosure relates. Each disclosure item set forth in the Disclosure Schedules shall relate only to
the specific Section of the Agreement that corresponds to the number of such Schedule and to any other Section of this Agreement to which it is reasonably apparent on the face of such disclosure that such disclosure relates. The information
contained in this Agreement, the Exhibits hereto and the Disclosure Schedules is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any Party hereto to any Third
