Item 1.01 Entry into a Material Definitive Agreement.

On October 1, 2019, Power Solutions International, Inc. (the “Company”) and Doosan Infracore Co., Ltd. (“Doosan”) entered into an addendum to the Supply Agreement, dated as of December 11, 2007 (the “Supply Agreement”), by and between Doosan and the Company, as amended by the prior addenda thereto (the “Addendum”).

The Addendum extends the term of the Supply Agreement to December 31, 2023, after which the agreement will automatically be extended for additional one-year terms unless a notice of termination is provided by either party six months prior to the scheduled expiration. The Addendum prohibits Doosan from specified product development in partnership with the Company’s existing or potential customers and competitors. The Addendum extends the Company’s exclusivity for the prescribed territory but carves out of the restriction the competing engine products supplied by General Motors Company and Weichai Power Co., Ltd. (“Weichai”). The Company committed to maximize sales and service opportunities on both Doosan and Weichai engine products, recognizing their different value proposition and target markets. The Addendum also updates the minimum product purchase commitments for the period 2019 through 2023, subject to reductions based on market declines in oil prices and defined prescribed payments to Doosan triggered by shortfalls in purchases made by the Company during each annual calendar period.

The Addendum is attached to this Current Report on Form 8-K as Exhibit 10.1 and is incorporated by reference herein. The foregoing summary of the Addendum is qualified in its entirety by the complete text of the Addendum filed herewith.

For further information regarding the Supply Agreement, see the copy of the Supply Agreement (as previously amended) filed as Exhibit 10.12 to Amendment No. 4 to the Company’s Current Report on Form 8-K dated April 29, 2011, filed with the Commission on August 12, 2011.

ADDENDUM #10

This Addendum #10 (“Addendum”) made and entered into this day of September 16, 2019 by and between DOOSAN INFRACORE CO., LTD., having its principal place of business at 7-11, Hwasu-dong, Dong-gu, Incheon, Korea (“SUPPLIER”) and POWER SOLUTION INTERNATIONAL, INC., an Illinois corporation (“PSI”), having its principal place of business at 201 Mittel Drive, Wood Dale, Illinois, USA 60191, United States (PSI and its affiliates shall collectively be referred to herein as “BUYER”)

WITNESSETH:

WHEREAS, SUPPLIER and BUYER are the parties to the Supply Agreement dated December 11, 2007, as amended from time to time with the following Addenda (together, the”Agreement”) dated:

December 27, 2007,

August 28, 2008,

September 30, 2008,

December 11, 2008,

November 18, 2009,

December 31, 2009,

June 19, 2012,

July 31, 2014, and

October 18, 2017;

WHEREAS, the parties agree to extend the term of the Agreement until December 31, 2023 with Buyer maintaining exclusivity for Products in the Territory under the conditions stated herein;

WHEREAS, Buyer agrees to pay certain amounts for shortfalls in target volumes under the terms stated herein and Supplier agrees to allow Buyer to sell Weichai product under the conditions stated herein;

WHEREAS, the parties have agreed to amend the Agreement as of the Effective date on the following terms and conditions.

Now, THEREFORE, in consideration of the mutual covenants and promises contained herein, both parties agree as follows:

SUPPLIER shall have the authority to independently develop its own engine platform to meet global emissions requirements, including but not limited to Euro Stage 2, 3, 4 and 5 as well as Environmental Protection Agency (EPA) standards. SUPPLIER will not perform any degradation/deterioration factor or EPA certification testing or application until January 2023. Independent development shall mean SUPPLIER will research and develop said engine platform by itself using its own resources and will not directly or indirectly partner with any third party, including without limitation, BUYER’s existing or potential customers including, but not limited to, [***] and/or any of BUYER’s distributors or competitors such as [***], in each case without the prior written consent of BUYER.

Other than products of General Motors (“GM”) and Weichai Power Co., Ltd. (“Weichai”) and/or any of their respective affiliates, BUYER will not be concerned or interested in products that have the same displacement or are designed to perform the same function as Products unless SUPPLIER is in breach of any term of this Agreement and/or fails to timely supply to BUYER with Products ordered hereunder in accordance with the terms hereof. If this provision or this Agreement is in or becomes in conflict with any other preexisting agreement to which BUYER and/or SUPPLIER or any of their affiliates is a party, the parties agree to negotiate in good faith modifications to this provision and this Agreement so as to eliminate such conflict.

Buyer will have access to distribute the Weichai engine platform for natural gas markets in North America. The Seller Produts and Weichai engine platforms have different value propositions and different target markets in North America and globally. Buyer will work to strategically position both products in the respective markets to maximize the sales and service opportunities of both engine platforms. Having this strategic control will help to allow Buyer to maximize the expansion of the Seller product range into the North American market while protecting market share with existing customers. Buyer will work to provide a rating matrix, detailing the power nodes and applications each product line will target.

This Agreement shall be in full force until December 31, 2023 and may be automatically extended for additional 1-year terms unless SUPPLIER or BUYER gives the other party written notice of its intention not to extend the Agreement at least 6 months prior to the date of scheduled expiration.

The purchase commitment amount listed above for each calendar year from BUYER is defined as the aggregate Products ordered by BUYER and invoiced by SUPPLIER pursuant to Article 4, in a calendar year defined as January 1 through December 31.

If the above purchase commitment amount is not met for any given year, for such year only, BUYER will compensate SUPPLIER for the shortfall as follows:

Notwithstanding the foregoing, if the Oil Price Threshold (as defined below) is triggered in any calendar year, the purchase commitment amount will be adjusted downward according to the following:

Payment of shortfall for any year will be disbursed in 2 equal installments: the first payment will be paid on March 31 and the second payment will be paid on June 30 of the following year.

For the purpose of this Agreement, “Oil Price Threshold” is defined as the oil price listed on West Texas Intermediate (“WTI”), settled at Cushing, Oklahoma (https://markets.businessinsider.com/commodities/oil-price?type=wti). This threshold shall be split into 2 levels, as follows:

IN WITNESS WHEREOF, the undersigned parties have executed this Addendum #10 as of the date listed above.
