on and in conformance with the design, technical and quality specifications set forth in Exhibit ‘A” hereto (the “Specifications”)
and in accordance with the production schedule set forth in Exhibit ‘B”. Unless otherwise agreed in writing by Buyer

Exhibit “B”. The pricing for the Products is subject to change as set forth in herein. Seller is obligated to pre-notify
Buyer ninety (90) days in advance to any price increases and Seller will obtain Buyer’s written acceptance prior to incurring
the costs, and at no time is Buyer obligated to pay price increases that do not comply with this requirement; provided the foregoing
notice provision shall not apply to change orders mutually executed by the Parties in accordance with Section 3 below. To

Agreement, Seller shall be bound by the PO when (a) Seller executes and returns an acknowledgment copy of a PO; (b) Seller commences
work on such Products; or (c) Seller ships such Products that conform to the Specifications, whichever occurs first. Provided Buyer’s

Notwithstanding anything
to the contrary contained herein, Buyer reserves the right at any time to request a proposed written change order or amendment
to this Agreement (along with a corresponding increase or decrease in the total Purchase Price and an extension of the time for
the performance of Seller’s obligations under this Agreement) concerning any of the following:

 

(a) changes to the quantity of Products
ordered, subject to Buyer’s minimum purchase obligation set forth in Section 1 and Seller’s maximum production
capacity set forth in Section 1, provided, that (i) Buyer gives at least 90 days’ notice of the quantity change,
(ii) the volume change for such subsequent quarter shall be no greater than 25% and Buyer must remain at such revised quantity
level for at least two calendar quarters beginning with the calendar quarter in which the volume change was implemented and (iii)
if the requested change exceeds 25% then the Parties shall discuss how to equitably manage such quantity change but neither party
shall unreasonably withhold the decision to proceed; and provided, further, that with respect to any such change
to the quantity: (I) the minimum commitment and dedicated capacity shall always apply and (II) the applicable Manufacturing Facility
will be reasonably level-loaded;

(b) changes to the Specifications,

(c) methods of shipment or packaging,
and/or

(d) changes to the dates of Product

to this Section 3 must be agreed upon by Seller in writing and thereafter, may result in (i) an adjustment to the Purchase
Price and (ii) an extension of the time for the performance of Seller’s obligations under this Agreement.

 

If Buyer’s failure
to timely perform its material obligations under this Agreement adversely affects Seller’s performance of its obligations
hereunder, Seller shall be entitled to a change order providing Seller with an (i) equitable extension of the time for the performance
of its obligations under this Agreement, and (ii) an increase in the Purchase Price to reflect the actual and reasonably substantiated
costs incurred by Seller, in each case, as a result of such delay by Buyer and as mutually agreed to by the Parties (it being understood
the Parties will negotiate in good faith any disputes regarding the calculation of the amount of any increase in the Purchase Price).
Notwithstanding the forgoing to the contrary, Buyer’s good faith dispute of an invoice shall not constitute a Buyer delay
pursuant to this Section 3.

law, regulation or standard, or the alteration, modification, revocation or change in interpretation of an existing law after the
execution date of this Agreement adversely impacts a Party’s performance of its obligations hereunder (“Change in
Law”), the affected Party shall be entitled to a change order providing the affected Party with an (i) equitable extension
of the time for the performance of its obligations under this Agreement, including, the case of Seller, the date for the completion
of any Product and (ii) applicable adjustment in the Purchase Price by the actual and reasonably substantiated costs incurred by
the affected Party in performing its obligations under this Agreement, in each case, as a result of such Change in Law.

4.
Specifications, Inspections and Testing, and Risk of Loss.

 

All Products ordered by
Buyer will comply with the Specifications. With respect to each Product, Seller shall perform the inspections and quality testing
procedures set forth on Exhibit “A” at the Manufacturing Facility prior to notifying Buyer that a Product is available
for inspection by Buyer. If any Products fail to meet such inspection or testing criteria, Seller shall remedy such Products until
they pass such inspection and testing criteria. Seller will provide five (5) business days of advance notice of the estimated Product
completion and inspection dates if Seller becomes awareness of any delays in the completion schedule of any of the Products. Seller
shall share with Buyer all inspection and testing results with respect to the Products, including reports as to the dimension measurements
of such Products. After a Product has passed such inspection and testing criteria, Buyer will have the right to inspect such Product
at the applicable Manufacturing Facility, within four (4) business days. In the event that Buyer fails to inspect a Product within
such four (4) business day period or fails to provide Seller with written notice of acceptance or rejection of such Product, the
applicable Product will be deemed to be accepted. Except for the inspections and testing conducted by Seller as contemplated in
this Section 4, costs and expenses of the Product inspections at the applicable Manufacturing Facility shall be borne solely
and exclusively by Buyer. Seller shall reimburse Buyer for any out-of-pocket costs and expenses incurred by Buyer with respect
to subsequent inspections of the Products due to any acts and omissions of Seller within thirty (30) days from the date of Buyer’s
visit to the applicable Manufacturing Facility. Accepted Products shall be delivered by Seller to the designated storage area of
the applicable Manufacturing Facility. Title and risk of loss to the Products transfers from Seller to Buyer when Seller has loaded
the Products onto Buyer’s carrier at the applicable Manufacturing Facility and thereafter any claims by Buyer that the Products
are defective or otherwise do not conform with the Specifications shall be treated as a warranty claim under Section 9.

 

5.
Price and Minimum Purchase Requirement.

 

The pricing is as set
forth on Exhibit ‘B’ hereto per the Specifications.

 

If the Buyer fails to
satisfy its total annual minimum commitment (set forth in Exhibit B) in the annual PO, Buyer shall pay to the Seller a fee equal
to the product of: (i)(A) the applicable annual minimum commitment number of Products less (B) the number of Products actually
ordered by the Buyer for the applicable calendar year; and (ii) the price per Product at the minimum commitment price (of
the 40’ Product) minus the BOM costs minus other direct costs that the Supplier may be able to avoid for the lost volume,
provided, that, Supplier shall use good faith efforts to minimize such unavoidable costs, and provided, further,
that the calculated amount in (ii) above shall not exceed [***]. Such fee will be payable in 4 installments on Jan 1st, April 1st,
July 1st, October 1st of the applicable calendar year. At the end of each year, the Parties will true up any amounts previously
paid under this Section during such year, to reflect the total volume purchased. If Buyer’s annual purchases exceed the applicable
annual minimum commitment number, then solely for the purposes of calculating the fee (if any) set forth in this paragraph for
the subsequent year, the number of Products in subsection (i)(A) above shall be reduced by the product of: (x) l0% and (y)(I) the
number of Products purchased in the prior year less (II) the applicable minimum commitment number of Products of the prior year.
If Buyer elects to purchase additional Products in excess of the production capacity set forth on Exhibit ‘B” and Seller
desires to sell such additional Products to Buyer, then the Parties shall negotiate in a good faith an amendment to the production
schedule set forth in Exhibit ‘B’ to reflect such increased production and execute such amendment prior to the commencement
of manufacturing such additional Products.

 

    6

     

    

 

Except for the adjustments
set forth in Exhibit B, Buyer shall not be billed at a price higher than the price set forth in this Agreement unless Buyer authorizes
a higher price in writing and signed by Buyer. Buyer shall have the right to audit and inspect, upon reasonable notice and during
regular business hours, all pricing, contracts, purchase orders and payment schedules applicable to Seller’s performance
of this Agreement. All pricing is inclusive of direct and indirect costs. Unless agreed to in writing by the Parties maintenance,
repair and overhaul costs as well as other consumables costs shall be borne by Seller. Seller shall identify all components to
the pricing and will provide Buyer on a quarterly basis with a costed bill of materials (“BOM”) with respect to the
Products. The Seller shall provide the direct labor hours for production on a quarterly basis. Buyer reserves the right to audit
quarterly submissions by Seller.

 

Seller shall be responsible
for all taxes, packing costs, import and custom duties on raw materials, personnel fees and all other costs, fees, and expenses
related to or incurred in connection with the manufacturing of the Products, including, but not limited to, any and all taxes on
consumables and equipment rentals and sales and use taxes related to materials and equipment utilized in manufacturing of the Product.

 

6.
Extra Charges.

 

No charges against Buyer
will be allowed for taxes, import duties, unless otherwise stated in this Agreement or specifically pre- agreed to in writing and
signed by Buyer in any PO. For clarity, all sales, use, excise, or similar taxes to be paid by Buyer must be itemized separately
in a PO and on invoices. Seller shall provide pre-written requests for payment by Buyer of non-recurring expenses or other one-time
expenses (‘‘NRE”) (that are not otherwise set forth on Exhibit “C” to this Agreement) to Buyer with
reasonable advanced notice prior to Seller’s request date to allow time for Buyer’s review and consent. At no time
will Buyer be liable for any NRE if not approved in writing by Buyer’s Supply Chain authorized representative prior to occurrence
of the NRE or extra charges. If Seller did not receive Buyer’s Supply Chain authorized written approval prior to the occurrence
of the NRE, then Seller is solely liable for those charges and expenses.

 

7.
Payment Terms and Aftermarket Sale.

 

Unless otherwise specified
in this Agreement, payment for Products shall be net [***] following the receipt by Buyer of a correct and valid invoice issued
by Seller after acceptance of a Product pursuant to Section 4. Seller shall accept payment in United States dollars by Automated
Clearinghouse (ACH) payment or as otherwise mutually agreed between the Parties. Invoices must be sent within sixty (60) days of
shipment. Seller hereby agrees not to directly or indirectly sell, or allow or facilitate direct or indirect sales of any Products
for use with Buyer’s products to any customer of Buyer without Buyer’s prior written consent to be granted or denied
at Buyer’s sole discretion. Seller shall sell to Buyer aftermarket parts at mutually agreed upon prices for the Products
that are in production at the applicable Manufacturing Facility. Seller shall provide Buyer with a written End of Life (“EOL”)
pre-notice not less than one-hundred twenty (120) days prior to the discontinuance of Products. Any amount due to Seller that are
not otherwise disputed in good faith by Buyer shall accrue interest from the date that it first became due and payable until the
date that it is paid at a monthly rate of one percent (1.0%) per month.

8.
Delivery.

 

Seller shall achieve completion
of each Product in accordance with the mutually agreed upon schedule set forth in Exhibit ‘B’. If, by reason of a Force
Majeure Event, Seller shall be delayed, wholly or in part, in meeting the date for the completion of any Product, Seller shall
be entitled to a change order providing Seller with an (a) equitable extension of the time for the performance of its obligations
under this Agreement, including an extended delivery date for the affected Product(s); provided that: (i) Seller provides Buyer
written notice of (A) the occurrence of such Force Majeure Event as soon as reasonably practicable, and in any event within forty-eight
(48) hours after Seller learns of such Force Majeure Event and (B) the particulars of such Force Majeure Event, including the impact
thereof on Seller’s performance of its obligations under this Agreement, within five (5) Business Days after Seller learns
of such Force Majeure Event; (ii) such extension will be of no greater duration than is justified by such Force Majeure Event;
and (iii) Seller uses its commercially reasonable efforts to overcome such delay. For purposes of this Agreement, a “Force
Majeure Event” shall mean any events or occurrences which are beyond the reasonable control of Seller and are not caused
by the negligence, willful acts or omissions or lack of the exercise of reasonable diligence of Seller, including, without limitation,
acts of God; acts of war or terrorism, civil disturbances, riots, insurrection or sabotage; fires or explosions; floods, earthquakes,
tornadoes or other natural disasters; power outages; orders or injunctions issued by any governmental authority. If a Force Majeure
Event extends over thirty (30) days and the Parties have not been able to agree in good faith upon a plan to mitigate the impact
of a Force Majeure Event, either Party shall be entitled to terminate this Agreement by notifying the other Party at no charge
to the other Party other than any amounts owed by one Party to the other Party that have accrued prior to the effective date of
termination (and in the case of amounts owed by Buyer, such amounts have accrued with respect to only Products that have been delivered
to and accepted by Buyer).

 

Unless otherwise provided
in this Agreement or any PO, no delivery required hereunder shall be made more than seven (7) days prior to the applicable delivery
date. The Parties acknowledge and agree that it would be extremely difficult and impracticable under the presently known and anticipated
facts and circumstances to ascertain and fix with precision the actual damages Buyer would incur should Seller fail to complete
any Product within twenty (20) days from the committed delivery date, and accordingly the Parties hereby agree that in such event,
Buyer shall be entitled to recover from Seller as liquidated damages for such delay, and not as a penalty, [***] of the Purchase
Price for each Product for each complete week (after the 20 day period following the specified date) that such Product has not
been completed after the corresponding date (the “Delay Liquidated Damages”), subject to a maximum amount of
Delay Liquidated Damages equal to [***] of the applicable Purchase Price. The Delay Liquidated Damages shall be due and payable
by Seller to Buyer within thirty (30) days after Seller’s receipt of an invoice therefor from Buyer. If multiple Products
are delayed, the first Product that is thereafter completed will correspond to the earliest scheduled completion date that has
been missed. Notwithstanding anything herein to the contrary, Delay Liquidated Damages shall not apply to delays caused by actions
or inactions of Buyer or delays that are otherwise excused by the terms of this Agreement. Should Seller be liable for Delay Liquidated
Damages, payment of the Delay Liquidated Damages shall be Buyer’s sole and exclusive remedy for Seller’s failure to
deliver the Products by the applicable delivery date. No provision of this Agreement or any PO for the delivery of Products in
installments shall be construed as making Seller’s obligation severable.

 

If Buyer is entitled to
claim Delayed Liquidated Damages on [***] or more of the Products supplied by Seller to Buyer in any rolling 12 month period, then
Buyer may terminate this Agreement upon 30 days’ prior written notice to Seller of its intent to terminate; provided that
Buyer must exercise such termination right within 45 days of the date upon which Buyer first becomes entitled to terminate this
Agreement pursuant to this paragraph and such termination right shall be in lieu of any termination right under Section 19.l(a)
hereof.

 

If Seller is late to Buyer’s
Purchase Order delivery date for more than one (1) week, Seller agrees to use commercially reasonable efforts at Seller’s
cost to improve the delivery, which may include but is not limited to, adding labor, paying overtime, pay premium freight costs
from Seller’s suppliers, and/or premium freight for delivering the Product to Buyer.

 

No Party shall export
or re-export, directly or indirectly, any technical information disclosed hereunder or direct product thereof to any destination
prohibited or restricted by the applicable export control regulations, including but not limited to the U.S. Export Administration,
without the prior authorization from the appropriate governmental authorities.

 

    8

     

    

 

9.
Warranty.

 

Seller warrants that the
Products shall be of good and workmanlike quality and new, and shall be in full conformity with the Buyer’s Specifications
and free from defects and deficiencies in materials and workmanship.

 

The foregoing warranties
shall survive the termination or expiration of this Agreement, except as provided below, and shall remain in full force and effect
for a period of twenty-four (24) months after the applicable Product has been accepted (or deemed accepted) by Buyer (the “Warranty
Period”); provided, however, that (i) upon a termination of this Agreement pursuant to Section 19.5(a) Seller’s
warranty obligations shall not survive such termination of this Agreement, and (ii) upon a termination of this Agreement pursuant
to Section 19.5(b), Seller’s warranty obligations with respect to any Products for which Seller has not received payment
from Buyer prior to such termination or expiration shall not survive such termination of this Agreement; provided, further, with
respect to any Product which has been repaired, replaced, or otherwise corrected during the preceding period, such repaired part
of the Product shall be automatically re-warranted by Seller for the balance of the Warranty Period; provided, that, in no case
shall the warranty for such repaired portion of the Product be less than 12 months. Seller will offer Buyer an optional extended
warranty to a total of thirty-six (36) months and this cost will be as quoted by Seller.

 

Seller will have a reasonable opportunity
to inspect any Product not meeting the foregoing warranties claimed by Buyer, and such defective Product shall (i) if Seller determines
that such defective Product can be repaired at the site where the Product is parked or stored when not in service (the “Bus
Lot”), be repaired at the Bus Lot, (ii) if Seller determines that such defective Product cannot be repaired at the Bus
Lot, be removed from the Bus Lot and repaired at a location determined by Seller at Seller’s cost or (iii) if Seller determines
that such defective Product cannot be repaired at the Bus Lot, be replaced, in each case, by Seller at its sole cost and expense,
including any shipping costs and expenses associated with shipping the defective Product from the Bus Lot and returning it back
to the Bus Lot. Upon Seller’s receipt of a notice of a defective Product from Buyer, Seller shall acknowledge receipt of
such notice within three (3) business days of its receipt thereof, provide an investigation and mobilization plan within five (5)
business days of its receipt thereof and mobilize its personnel to the applicable Bus Lot to perform its obligations under this
Section 9 as soon as reasonably practicable thereafter. For the avoidance of doubt, Seller shall be responsible for all
costs associated with any such repair or replacement, including, but not limited to, transportation and access to the defective
Product; provided that the Parties will use commercially reasonable efforts to mitigate the costs of disassembly, reassembly, transport,
crane hire, and other activities required in connection with repairing and replacing defective Product and to avoid such costs,
if possible.

 

Seller’s obligations
under this Section 9 do not apply to a defect to the extent proven to be primarily caused by (i) normal and ordinary wear
and tear and/or erosion or corrosion in a Product (not caused by Seller’s manufacture of the Product); (ii) a Force Majeure
Event; or (iii) any negligence, accident, or abuse of a Product not attributable to Seller or (iv) the improper storage, installation,
use, operation, or maintenance of a Product. EXCEPT FOR THE EXPRESS WARRANTIBS AND REPRESENTATIONS SET FORTH IN THIS SECTION 9
OR ELSEWHERE AGREED TO AND SIGNED IN WRITING BY SELLER, SELLER DOES NOT MAKE ANY OTHER EXPRESS WARRANTIES, OR ANY IMPLIED WARRANTIES
OR REPRESENTATIONS, OF ANY KIND IN RESPECT OF A PRODUCT OR ANY WORK PERFORMED BY SELLER HEREUNDER, INCLUDING ANY IMPLIED WARRANTY
OF MERCHANTABILITY, NON-INFRINGEMENT OR FITNESS FOR PURPOSE. THE REMEDIES PROVIDED FOR IN THIS IN THIS AGREEMENT WITH RESPECT TO
A PRODUCT OR ANY WORK WHICH FAILS TO SATISFY SELLER’S WARRANTIES DURING THE WARRANTY PERIOD SHALL BB THE SOLE AND EXCLUSIVE
REMEDIES FOR BUYER AS A RESULT OF SUCH FAILURE.

 

    9

     

    

 

10.
Confidentiality.

 

Unless otherwise
agreed by a Party (the “Disclosing Party”) in writing, the other Party (the “Receiving
Party”)shall keep confidential and not disclose to any third party, any confidential and/or proprietary materials
provided by the Disclosing Party to the Receiving Party in connection with the Receiving Party’s performance of this
Agreement or prepared by the Receiving Party specifically for the Disclosing Party pursuant to this Agreement, including but
not limited to any drawings, masters, software, specifications, raw materials, components, data, business and financial
information or plans, customer lists or other customer information (“Confidential Information”); provided,
however, that Confidential Information shall not include information (i) which at the time of disclosure is in the public
domain; (ii) which after disclosure becomes a part of the public domain without any breach by the Receiving Party or an
affiliate and/or their respective personnel of the terms of this Section 10; (iii) which can be established was already in
the Receiving Party’s possession at the time of disclosure and was not acquired directly or indirectly from the
Disclosing Party under a then existing obligation of confidentiality to the Disclosing Party; (iv) which can be established
was received by the Receiving Party from a third party, after the time of disclosure by the Disclosing Party, which third
party did not acquire it directly or indirectly from the Disclosing Party under an obligation of confidentiality; or (v)
which is developed independently by the Receiving Party without having reviewed, used or made reference to relevant parts of
the Confidential Information of the Disclosing Party as disclosed by the Disclosing Party or use of or reference to the
Confidential Information of the Disclosing Party or without breach of any of the provisions of this Agreement. Seller may
provide the Buyer’s Confidential Information to subcontractors who have a need to know such information for the
performance of any work hereunder and who are advised of the confidential nature of such Confidential Information and Seller
shall remain responsible for the breach of this Agreement by any subcontractor. The Receiving Party may disclose Confidential
Information in the event, but only to the extent, that, based upon advice of counsel, the Receiving Party is required to do
so by the disclosure requirements of any Applicable Law. Prior to making or permitting any such disclosure (except in the
case of any disclosure to the United States Securities and Exchange Commission), the Receiving Party shall provide the
Disclosing Party with prompt written notice of any such requirement so that the Disclosing Party (with the Receiving
Party’s assistance if requested) may seek a protective order or other appropriate remedy. The Receiving Party shall not
make any copies of Confidential Information except as specifically authorized by the Disclosing Party in writing or as
necessary for the Receiving Party to perform its obligations under this Agreement. At the completion of this Agreement, or
upon the Disclosing Party’s request, the Receiving Party shall promptly return to the Disclosing Party all Confidential
Information not consumed in the performance of this Agreement, together with any copies in the Receiving Party’s
possession. The Receiving Party shall use Confidential Information solely for the Receiving Party’s performance of its
obligations under this Agreement, and Seller shall not, without Buyer’s prior written consent, directly or indirectly
use Confidential Information or information derived therefrom in performing services or providing Buses for any other
customer of Seller, or any other person or entity. It is understood and agreed that money damages would not be a sufficient
remedy for any breach of this Section 10 and that the Disclosing Party shall be entitled to equitable relief, including
injunction and specific performance, as a remedy for any such breach. Such remedies shall not be deemed to be the exclusive
remedies for a breach of this Section but shall be in addition to all other remedies available at law or equity.
Notwithstanding anything to the contrary herein, Buyer acknowledges that Seller may be required to provide access to Its
facilities to Seller’s other customers, and the provision of such access shall not, by itself, be deemed a violation of
Seller’s confidentiality obligations set forth in this Section 10.

 

    10

     

    

 

11.
Intellectual Property and Development.

 

Each Party acknowledges
and consents that the other Party, its affiliates and/or its technology providers are the sole owners of any intellectual or industrial
property rights over any and all the designs, drawings, plans and Specifications in relation to the Products or Tooling, and, in
general, any element of the Products, including the specifics of the Products production process and the parameters of manufacture
and materials, which in each case have been solely developed by such other Party, its affiliates and/or its technology providers;
provided, however, any intellectual or industrial property rights, including any improvements thereto, developed jointly by the
Parties, shall be jointly owned by the Parties, with the exception that any IP developed jointly by the Parties but paid for by
Buyer shall be owned by Buyer. In connection with such jointly owned intellectual property rights, each Party hereby grants to
the other Party a perpetual, royalty-free, paid-up license to make, use, and sell products and processes that utilize such jointly
developed intellectual property rights, to the extent that they can be utilized without infringing on any intellectual property
rights owned solely by the other Party.

 

All conceptions, ideas,
innovations, discoveries, inventions, compositions, material and methods, whether or not patentable or susceptible to any other
form of legal protection, made or derived specifically for the Products during performance under the Agreement (“Bus Resultant
Technology”) solely by a Party or its Affiliates without use of or reliance upon the other Party’s intellectual
property or confidential information and all rights therein shall be owned solely by such Party (or its affiliate); provided, however,
any Bus Resultant Technology developed jointly by the Parties shall be jointly owned by the Parties. In connection with such jointly
owned Bus Resultant Technology, each Party hereby grants to the other Party a perpetual, royalty-free, paid-up license to make,
use, and sell products and processes that utilize such jointly developed Bus Resultant Technology, to the extent that they can
be utilized without infringing on any Bus Resultant Technology owned solely by the other Party.

 

All conceptions, ideas,
innovations, discoveries, inventions, compositions, material and methods, whether or not patentable or susceptible to any other
form of legal protection, made or derived specifically for the Product manufacturing process during performance under the Agreement
(“Bus Manufacturing Resultant Technology”) solely by a Party or its affiliates without use of or reliance upon
the other Party’s intellectual property or confidential information and all rights therein shall be owned solely by such
Party (or its Affiliate); provided, however, any Bus Manufacturing Resultant Technology, developed jointly by the Parties shall
be jointly owned by the Parties. Each Party and any of its Affiliates shall be entitled to the use of such jointly owned Bus Manufacturing
Resultant Technology without the consent of the other Party, by means of a free, worldwide, non-exclusive and non-transferable
license.

 

    11

     

    

 

12.
Tooling.

 

Seller has developed certain
molds and plugs, as set forth in Exhibit C, on behalf of Buyer that will be used to manufacture the Products (the “Tooling”)
pursuant to one or more stand-alone POs. Should additional tooling be required to meet the volume requirements set forth in this
Agreement, Buyer shall purchase the additional tooling pursuant to a stand-alone PO. Any contractual warranties or other contractual
obligations of Seller with respect to the Tooling are solely intended for Buyer’s benefit and no benefits, rights, duties
or obligations are intended as to any third parties other than Buyer. Except as expressly set forth in a PO, in Exhibit C, or other
mutually agreed upon writing by Buyer and Seller, Seller disclaims all other express and Implied warranties with respect to the
Tooling. Seller agrees that, unless otherwise agreed to by the Parties, all fixtures and all Tooling developed on behalf of Buyer
to be used to manufacture the Products, whether purchased directly or purchased separately as part of the purchase price of the
Product, shall be and remain the sole and exclusive property of Buyer (collectively, “Buyer’s Property”).
Seller shall assume all risk of death or injury to person or damage to property arising from or related to Buyer’s Property
and the use of Buyer’s Property except as the result of the Buyer’s negligent acts or omissions. Seller shall treat
all Buyer’s Property with due care and diligence, constantly keeping it ready for operation. Seller bears the risk of loss
of and damage to Buyer’s Property while under Seller’s direct or indirect care, custody or control. Unless otherwise
agreed to in writing between the Parties, Seller is solely responsible for inspecting, testing and approving all Buyer’s
Property prior to any use. Buyer’s Property will be housed, maintained, repaired and replaced by Seller at Seller’s
expense in good working condition capable of producing Products meeting all applicable specifications; provided that Buyer shall
be responsible for repairing and replacing any Buyer’s Property that was not provided by or manufactured by Seller. Buyer’s
molds being utilized for manufacturing the Products will be housed at Seller’s expense during the term of this Agreement,
will not be used by Seller for any purpose other than the performance of this Agreement or a PO issued hereunder, will be clearly
and conspicuously marked and labeled by Seller as the property of Buyer, and will not be moved from Seller’s premises without
Buyer’s prior approval. Storage of Buyer’s plugs, and molds not being utilized for manufacturing the Products will
be charged to Buyer at the rates set forth on Exhibit “C”. Seller will, at its own expense, insure Buyer’s Property
with full fire and extended coverage insurance for its replacement value, and Seller, at Buyer’s request, shall deliver certificates
evidencing such insurance upon request from Buyer. Any replacement of Buyer’s Property will become Buyer’s property
(and thereafter will constitute “Buyer’s Property” hereunder). Seller may not release or dispose Buyer’s
Property to any third party without the express, prior written permission of Buyer. Buyer will have the right to enter Seller’s
premises to inspect Buyer’s Property and Seller’s records regarding Buyer’s Property with reasonable prior notice
to Seller. Only Buyer (or Buyer’s affiliates) has any right, title or interest in Buyer’s Property, except for Seller’s
limited right, subject to Buyer’s sole discretion, to use Buyer’s Property in the manufacture of Products in accordance
with the terms of this Agreement. Seller shall not grant or allow any security interest, mortgage, charge, lien or any other encumbrance,
claim or right on any of Buyer’s Property. Buyer and its affiliates have the right to take immediate possession of Buyer’s
Property upon termination of this Agreement and provided Buyer is not in breach of this Agreement (including its payment obligations
for undisputed invoices) at any time without payment of any kind. Seller, its affiliates and their employees agree to cooperate
with Buyer if Buyer elects to take possession of Buyer’s Property and shall return Buyer’s Property to Buyer as provided
herein, to a destination specified by Buyer, in good condition, except for normal wear and tear. Seller acknowledges that Buyer’s
Property shall constitute “Confidential Information” hereunder and includes proprietary and confidential information,
regardless of whether such information is marked or identified as confidential, and is delivered to Seller on a confidential and
nonpublic basis for the purpose of performing this Agreement 01· a PO issued hereunder only. If Buyer has agreed to reimburse
Seller for Buyer’s Property, invoices for such Buyer’s Property will be issued by Seller, and Buyer shall pay such
invoices within sixty (60) days of receipt.

 

Risk Mitigation.
During the Term, Seller commits to maintain an additional set of tooling, at Sellers expense, at a second facility or alternate
location in the event the primary facility is unable to produce Products.

 

13.
Indemnification; Limitation of Liability.

 

Each Party (the “Indemnifying
Party”) agrees to indemnify, defend, and hold the Indemnified Parties harmless upon an Indemnified Party’s demand
from and against all losses, damages, liability, actions, judgments, costs, and expenses (including, but not limited to, reasonable
attorneys’ fees and other expenses of litigation), suffered, incurred, or asserted by a third party against any Indemnified
Party for personal injury or property damage that arises from or out of a breach of this Agreement, or the negligent acts or omissions
or willful misconduct of the Indemnifying Party in its performance of its obligations under this Agreement.

 

    12

     

    

 

Buyer will defend, indemnify,
and hold harmless Seller and Seller’s owners, officers, directors, and employees (individually and collectively, a “Seller
Indemnified Party”), at Buyer’s expense, from any third party claim, action, suit, or proceeding against a Seller Indemnified
Party (a “Seller Infringement Claim”) to the extent that such Seller Infringement Claim based upon an allegation that
Products (and the design and Specifications of the Products of Buyer) infringe any Intellectual Property Right of any third party.
Buyer will indemnify a Seller Indemnified Party for any judgments, settlements, reasonable costs, and reasonable attorneys’
fees resulting from a Seller Infringement Claim. Buyer’s obligations under this Section are conditioned upon the following:
(i) upon becoming aware of a Seller Infringement Claim, a Seller Indemnified Party providing to Buyer prompt written notice of
the Seller Infringement Claim; (ii) a Seller Indemnified Party gives to Buyer sole authority and control of the defense and/or
settlement of the Seller Infringement Claim; provided, however, that Buyer shall not enter into any settlement agreement that binds
Seller in any way without the consent of Seller, which consent shall not be unreasonably withheld, delayed, or conditioned; and
(iii) a Seller Indemnified Party provides all reasonable information and assistance requested by Buyer, at Buyer’s expense,
to handle the defense and/or settlement of the Seller Infringement Claim. A Seller Indemnified Party, at its expense, may hire
legal counsel of its choice to participate in an advisory capacity in discussions, negotiations, or proceedings of the Seller Infringement
Claim.

 

Seller will defend, indemnify,
and hold harmless Buyer and Buyer’s owners, officers, directors, and employees (individually and collectively, a “Buyer
Indemnified Party”), at Seller’s expense, from any third party claim, action, suit, or proceeding against a Buyer
Indemnified Party arising out of or related to a claim (a ‘‘Buyer Infringement Claim”) to the extent that such
Buyer Infringement Claim is based upon an allegation that Seller’s intellectual property in the Products infringe any Intellectual
Property Right of any third party, Seller will indemnify a Buyer’s Indemnified Party for any judgments, settlements, reasonable
costs, and reasonable attorneys’ fees resulting from a Buyer’s Infringement Claim. Seller’s obligations under
this Section related to any Buyer Infringement Claim are conditioned upon the following: (i) upon becoming aware of an Buyer Infringement
Claim, a Buyer Indemnified Party providing to Seller prompt written notice of the Buyer Infringement Claim; (ii) a Buyer Indemnified
Party gives to Seller sole authority and control of the defense and/or settlement of the Buyer Infringement Claim; provided, however,
that Seller shall not enter into any settlement agreement that binds Buyer in any way without the consent of Buyer, which consent
shall not be unreasonably withheld, delayed, or conditioned; and (iii) a Buyer Indemnified Party provides all reasonable information
and assistance requested by Seller, at Seller’s expense, to handle the defense and/or settlement of the Buyer Infringement
Claim. A Buyer Indemnified Party, at its expense, may hire legal counsel of its choice to participate in an advisory capacity in
discussions, negotiations, or proceedings of the Buyer Infringement Claim.

 

In no event will either
party (and such Party’s parent company, affiliates, trustees, representatives, contractors, consultants and agents) be liable
to the other party for any indirect, incidental, consequential, special or punitive damages, or for loss of profits or revenue,
whether in an action in contract, tort, contribution, strict liability, or otherwise. Each Party acknowledges and agrees that the
following are not, and shall not be interpreted or construed as, consequential damages for the purposes of this Agreement:  (i) the
Delay Liquidated Damages; (ii) damages for which a Party is liable to the other Party (and other Indemnified Parties) pursuant
to the indemnification obligations set forth in Section 13 of this Agreement; (iii) damages incurred by a Party (and its parent
company, affiliates, trustees, representatives, contractors, consultants and agents) by reason of any fraudulent or willful misconduct
of the other Party or its contractors or agents; and (iv) damages incurred by a Party as a result of a breach by the other Party
of its obligations under Section 10. Except for claims referenced in subsection (iv) of the preceding sentence, Buyer’s cumulative
liability under the Agreement and all PO’s will not exceed [***], even if a term of this Agreement or any PO fails of its
essential purpose. Notwithstanding anything to the contrary contained in this Agreement, the total aggregate annual liability of
Seller on any claims of any kind, whether in contract, or otherwise, arising out of or related to this Agreement shall be limited
to [***] of the aggregate amount set forth in the previous calendar year’s invoices issued
to Buyer by Seller under this Agreement; provided however,
in no event shall the limitation in the preceding sentence be less than [***], excluding
any insurance recoveries by Seller under the insurance required by this Agreement or recoveries
by Seller from third parties. The limitation set forth in this Section 13 shall not apply
to claims arising from the fraud or willful misconduct of Seller.

 

    13

     

    

 

14.
POs.

 

Within 14 days of the
Effective Date, Buyer will issue one or more POs for Products for the period from January 1, 2018 through December 31, 2018. For
subsequent years, Buyer will issue on or more POs for the annual volume by October 15th of the preceding year. The Parties
will use commercially reasonable efforts to structure the completion schedule under each Purchase Order such that Seller will supply
to Buyer the Products in a relatively equalized manner throughout the applicable period. Seller agrees that it must acknowledge
the Buyer’s Purchase Order within ten (10) days from the Buyer’s notification. If Seller fails to send an acknowledgment
within ten (10) days, Seller will be deemed to have accepted the change to any Purchase Order. If such Purchase Order complies
with the requirements of this Agreement, Seller shall review and accept such Purchase Order as set forth in Section l; provided,
however, Seller shall not be obligated to accept any Purchase Orders that do not comply with the requirements of this Agreement,
including those which exceed the number of Products set forth in the production schedule in Exhibit ‘B’.

 

15.
Insurance. 

 

During the term of this
Agreement and for a period of one (1) year thereafter, Seller shall, at its own expense, maintain and carry insurance (in forms
and amounts reasonably prudent for Seller’s business and Seller’s performance of this Agreement) in full force and
effect which includes, but is not limited to, commercial general liability (including products/completed operations and contractual
liability coverage) in a sum no less than $5,000,000; provided that Seller may satisfy this coverage requirement through a combination
of one or more base policies together with an excess coverage insurance policy. Upon Buyer’s request, Seller will furnish
certificates of insurance and any renewals, evidencing that satisfactory policies are in full force and effect.

 

16.
Assignment and Subcontracting.

 

Except as otherwise set
forth in this Section 16, neither Party may assign, convey or transfer this Agreement, or any portion thereof, or otherwise delegate
its responsibilities hereunder, without the prior written consent of the other party. Seller shall not enter into a subcontract
with any other party (other than workers that are independent contractors of Seller that are co-located in the applicable Manufacturing
Facility) for the furnishing of any completed or substantially completed Products described in this Agreement or any PO without,
in each case, Buyer’s prior written consent. Either Party may assign this Agreement without the consent of the other Party
to an affiliated entity or to a successor-in-interest in the event of a merger, reorganization or sale of all or substantially
all of the stock, assets or business; provided in this case of such an assignment by Seller, the assignee must have the capability
to perform the obligations of Seller under this Agreement and not be a direct competitor of Buyer. In no event shall the sale of
stock of Buyer to any third party be considered an assignment of this Agreement. Subject to the foregoing, the provisions of this
Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns. Any assignment
or transfer of this Agreement in violation of this Section shall be null and void.

 

17.
Compliance with Laws.

 

Each Party shall at all
times comply with all applicable laws, regulations, rules, and orders in connection with the performance of such Party’s
obligations under this Agreement. Seller shall provide all product information related to the handling of the Products purchased
under this Agreement as may be required by law. Upon request, Parties agrees to provide the other Party with information and certifications
required to demonstrate compliance with applicable laws and regulations for Products supplied under this Agreement.

 

    14

     

    

 

Each Party warrants and
represents that prior to the execution of this Agreement it has not taken any action, which act or failure to act would have violated
this Section 17.

 

Notwithstanding anything
to the contrary herein, in the event of a breach by a Party of its representations, warranties, and covenants in this Section 17
that could reasonably be expected to materially and adversely affect such Party’s ability to carry out its obligations under
this Agreement, the other Party may, by written notice to such breaching Party, terminate this Agreement with immediate effect
and this Agreement shall thereupon terminate with no further obligation of any Party to the other Party, other than those that
arose prior to the date of termination under this Section 17, or that otherwise survive the terminate of this Agreement.

 

Seller represents and
warrants that Seller’s products satisfy the Buy America requirements of 49 CFR 661 and Seller shall provide certification
of compliance with Buy America with each Product shipment in a form reasonably acceptable to Buyer.

 

18.
Waiver; Amendment.

 

A waiver of a breach of
any term of this Agreement or any PO hereunder will not be construed as a waiver of any succeeding breach of that term or as a
waiver of the term itself. A party’s performance after the other’s breach shall not be construed as a waiver of that
breach. No failure or delay by either party to enforce or take advantage of any provision or right under this Agreement or any
PO hereunder shall constitute a subsequent waiver of that provision or right, nor shall it be a waiver of any of the other terms
and conditions of this Agreement or any PO hereunder. Neither this Agreement nor any provision herein shall be amended or modified
orally or by course of conduct, but only by a written agreement signed by the Parties.

 

19.
Termination.

 

19.1
No later than 12 months prior to the expiration of the term, the Parties shall decide whether (i) this Agreement shall automatically
expire or (ii) the term shall be extended by mutual agreement, including agreement on any amendments to the terms and conditions

Amendment
No. 1 to Amended and Restated Product Supply Agreement

 

This Amendment No. 1 (the “Amendment”)
is entered into by and between Proterra Inc (“Proterra” or “Buyer”) and TPI
Inc. (“TPI” or “Seller”) effective December 31, 2018 (the “Amendment
Effective Date”), and amends the Amended and Restated Product Supply Agreement entered into by and between Proterra
and TPI effective November 3, 2017 (the “Agreement”). Proterra and TPI may be referred to herein individually
as a “Party” and collectively as the “Parties”. Capitalized terms used but
not defined herein shall have the meaning ascribed to such terms in the Agreement.

 

RECITALS

 

WHEREAS, the Agreement
governs TPI’s manufacture and supply of, and Proterra’s purchase of, forty-foot (40’) and thirty five-foot (35’)
composite bus bodies in accordance with the technical specifications, pricing, purchase commitment and production schedule set
forth therein (collectively, the “Bus Program”);

 

WHEREAS, the Parties
desire to amend the Agreement to add a non-recurring expense (NRE) payable by Proterra to TPI related to the modification of the
35’ bus body design; and

 

WHEREAS, the Parties
also desire to amend, among other things, the Agreement’s price schedule and minimum volume commitments to align with TPI’s
current production capacity and costs under the Bus Program.

 

NOW, THEREFORE, in consideration
of the mutual covenants, terms and conditions set forth herein, and for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Parties agree as follows:

 

ARTICLE I

 

AMENDMENTS TO THE AGREEMENT

 

		1.	NRE Payment. Proterra shall make non-recurring engineering (NRE) payments to TPI related to
the modification of the 35’ bus body design. These payments will be broken into two phases but are reflective of the [***]
for the 35’ bus body program: (i) upon execution of this Amendment, TPI shall submit an invoice to Proterra for [***]
to be paid in [***] equal, successive monthly installments of [***] (the “Monthly NRE Payment”); and
(ii) starting the week of [***], TPI shall submit a weekly invoice to Proterra for [***] (the “Weekly NRE Payment”)
[***] (the “Production Schedule”). Subject to a Force Majeure Event, if TPI fails to meet the Production
Schedule for any week(s) during the Weekly NRE Payment’s [***], TPI shall forfeit, and Proterra shall have no payment obligation
related to, the Weekly NRE Payment for that week. If TPI meets the Production Schedule every week during the [***], the Weekly
NRE Payment will total [***]. Each week under the Production Schedule is distinct such that if TPI meets or exceeds the Production
Schedule for a particular week, there will be no impact or carry-over to another week’s production requirements or Weekly
NRE Payment. TPI agrees to use best efforts and operate in good faith in this regard, and not hold back shipments in one week if
the Production Schedule is in jeopardy in order to secure the requirements for the following week.

 

		2.	Revised Specifications. (i) Part Number [***] referenced in Section 1 of Exhibit ‘A’
of the Agreement is hereby deleted and replaced with the following part numbers: [***] and [***]; and (ii) [***] referenced

1 (a) and (b) of “2018 – 2022 Pricing” stating that TPI may adjust the cost of the 35’ bus body based on
bill of material (BOM) consumptions and direct labor costs following TPI’s production of the [***] and [***] 35’ bus
body, is hereby deleted and replaced in its entirety as follows:

 

a. On [***], Seller may adjust the
cost of the 35’ bus body to the extent, if any, that Seller is able to substantiate in detail the BOM and direct labor costs
in excess of the BOM and direct labor costs used to calculate the [***] “35’ TPI Price Ceilings” set forth in
this Exhibit ‘B’s “2018 – 2022 Pricing” table. In no event shall this price adjustment result in
a price greater than [***] per 35’ bus body. Further, this price adjustment is subject to TPI (i) identifying all components
to the pricing with a costed BOM and (ii) providing the direct labor hours for production, each on a quarterly basis, pursuant
to Section 5 of this Agreement. For the avoidance of doubt, the [***] price ceiling in this Subsection 3(a): (i) shall apply to
any additional BOM, direct labor costs, or NRE incurred in order to successfully manufacture and produce the 35’ bus body
as contemplated by the Revised Specifications; and (ii) shall not apply to any changes submitted by the Buyer under Section 3 of
the Agreement after the Amendment Effective Date that modify the 35’ bus body beyond the 35’ bus body contemplated
by the Revised Specifications.

 

b. In accordance with this Exhibit
‘B’s “2018 – 2022 Pricing” table, any cost adjustment to the [***] 35’ bus body price hereunder
(i) shall be set at “[***]” and (ii) subject to the same price reductions in [***] and [***]. Example: If the
[***] 35’ bus body price is adjusted to [***], (i) the [***] 35’ bus body price at [***] would be [***] and [***],
respectively; and (ii) the [***] and [***] 35’ bus body price at “[***]” would be [***] and [***], respectively.
