Re: Equity Commitment Letter

Ladies and Gentlemen:

It is contemplated that pursuant to the terms of that certain Agreement and Plan of Merger, dated as of June 28, 2019 (as amended, restated, supplemented or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”), by and among, Highpower International, Inc., a Delaware corporation (the “Company”), HPJ Parent Limited, a newly-formed exempted company with limited liability incorporated under the laws of the Cayman Islands (“Parent”), and HPJ Merger Sub Corp., a Delaware corporation that is a wholly-owned subsidiary of Parent (“Merger Sub”), Merger Sub will merge with and into the Company, with the Company being the surviving company (the “Merger”). Capitalized terms used but not otherwise defined herein have the meanings ascribed to such terms in the Merger Agreement.

It is contemplated that pursuant to that certain Equity Commitment Letter (the “EIC Equity Commitment Letter”) issued by Essence International Capital Limited (“Essence International Capital”) to Parent on June 28, 2019, Essence International Capital has committed to contribute, as an equity contribution to Parent, an aggregate amount equal to US$51,136,733.00 to fund the transactions as contemplated under the Merger Agreement, provided that if Essence International Advanced Products and Solutions SPC – Essence Growth Company Fund SP, a segregated portfolio of Essence International Advanced Products and Solutions SPC, an exempted company incorporated with limited liability and registered as a segregated portfolio company under the laws of the Cayman Islands (the “Sponsor”) has irrevocably contributed as an equity contribution to Parent any proceeds to fund the transactions as contemplated under the Merger Agreement, Essence International Capital’s equity contribution will be reduced on a dollar-for-dollar basis by the exact amount of such equity contribution by the Sponsor.

The Sponsor is pleased to offer this commitment, subject to the terms and conditions contained herein, to purchase equity interests in Parent. Notwithstanding anything to the contrary contained herein, this commitment shall not be construed as an amendment, waiver or modification of any provision of the EIC Equity Commitment (including all third party beneficiary rights of the Company thereunder), which shall remain in full force and effect.

1.Commitment. The Sponsor hereby agrees to contribute, as an equity contribution to Parent, an aggregate amount equal to US$45,136,733.00 (the “Contribution”), subject to the terms and conditions hereof. The proceeds of the Contribution shall be used by Parent, to the extent necessary, to (i) fund (or cause to be funded) a portion of the Exchange Fund and any other amounts required to be paid by Parent or Merger Sub pursuant to the Merger Agreement and (ii) pay (or cause to be paid through Parent or Merger Sub) related fees and expenses or reimbursements of expenses (which, for the avoidance of doubt, shall not include the Parent Termination Fee or any Guaranteed Obligations with respect to the Parent Termination Fee that may become payable pursuant to the Limited Guarantee given by the Sponsor), in each case, pursuant to and in accordance with the terms of, and subject to the conditions of, the Merger Agreement. Notwithstanding anything else to the contrary in this letter agreement, the aggregate amount of liability of the Sponsor under this letter agreement shall at no time exceed the aggregate amount of the Contribution less any portion of the Contribution that has been funded in accordance with the terms hereof.

2.Closing Conditions. The Sponsor’s obligation to make the Contribution pursuant to this letter agreement is subject to the satisfaction, prior to or contemporaneously with the Closing, of the following conditions: (a) the satisfaction or waiver at the Closing of all conditions precedent to the obligations of Parent and Merger Sub to consummate the transactions contemplated by the Merger Agreement set forth in Article VIII thereof (in each case, other than any conditions that by their nature are to be satisfied at the Closing, but subject to the prior or substantially concurrent satisfaction or waiver of such conditions) and (b) the substantially contemporaneous consummation of the Closing.

3.Enforcement. This letter agreement may only be enforced (i) by Parent or (ii), to the extent that the Company has obtained an order of specific performance pursuant to, and subject to the conditions in, Section 10.06 of the Merger Agreement, by the Company, as a third party beneficiary of the rights granted to Parent hereby, to seek specific performance of the Sponsor’s obligations hereunder. The parties agree that irreparable damage would occur in the event that any of the provisions of this letter agreement were not performed in accordance with their specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any damages.

4.Non-Recourse. Notwithstanding anything that may be expressed or implied in this letter agreement, by its acceptance hereof, Parent acknowledges and agrees that (a) notwithstanding that the Sponsor may be a limited liability entity, no recourse hereunder or under any documents or instruments delivered in connection herewith may be had against any Affiliate of the Sponsor, any former, current or future director, officer, employee or agent of the Sponsor or of its Affiliates, any former, current or future holder of any equity interests or securities of the Sponsor (whether such holder is a limited or general partner, member, manager, stockholder or otherwise), any former, current or future assignee of the Sponsor or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder, Affiliate, controlling person, representative or assignee of any of the foregoing (each such person or entity, a “Related Person”), whether by the enforcement of any judgment or assessment or by any legal or equitable proceeding or by virtue of any statute, regulation or other applicable law, and (b) no personal liability whatsoever will attach to, be imposed on or otherwise be incurred by Related Persons in connection with this letter agreement or any documents or instruments delivered in connection herewith for any claim based on, in respect of or by reason of such obligations or by their creation.

6.No Assignment. Neither this letter agreement nor any of the rights, interests or obligations hereunder shall be assignable without the prior written consent of the Sponsor (in the case of an assignment by Parent) or Parent (in the case of an assignment by the Sponsor), and, in either case, the Company, except that, without the prior written consent of Parent or the Company, the rights, interests or obligations under this letter agreement may be assigned and/or delegated, in whole or in part, by Sponsor to one or more of its Affiliates or to one or more private equity funds sponsored or managed by any such Affiliate; provided that no such assignment shall relieve the undersigned of its obligations hereunder. Any purported assignment of this commitment in contravention of this Section 6 shall be void.
