ITEM (9) ACKNOWLEDGEMENT & SIGNATURE (continued from reverse side) Under penalty of perjury, I hereby certify that the Social Security or Tax ID Number and the information provided on this stock order form are true, correct and complete and that I am not subject to back-up withholding. It is understood that this stock order form will be accepted in accordance with, and subject to, the terms and conditions of the plan of reorganization and minority stock issuance of HarborOne Bank and HarborOne Mutual Bancshares described in the accompanying prospectus. Federal regulations prohibit any person from transferring, or entering into any agreement, directly or indirectly, to transfer the legal or beneficial ownership of subscription rights or the underlying securities to the account of another. HarborOne Bank, HarborOne NorthEast Bancorp, Inc., and HarborOne Mutual Bancshares will pursue any and all legal and equitable remedies in the event they become aware of the transfer of subscription rights and will not honor orders known by them to involve such transfer. Under penalty of perjury, I certify that I am purchasing shares solely for my account and that there is no agreement or understanding regarding the sale or transfer of such shares, or my right to subscribe for shares.

CERTIFICATION FORM I ACKNOWLEDGE THAT THIS SECURITY IS NOT A DEPOSIT OR SAVINGS ACCOUNT AND IS NOT FEDERALLY INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR BY ANY OTHER GOVERNMENT AGENCY OR THE SHARE INSURANCE FUND. THE ENTIRE AMOUNT OF AN INVESTOR’S PRINCIPAL IS SUBJECT TO LOSS. I further certify that before purchasing the common stock of HarborOne NorthEast Bancorp, Inc. (the “Company”), I received a prospectus of the Company dated May , 2019 relating to such offer of common stock. The prospectus that I received contains disclosure concerning the nature of the common stock being offered by the Company and describes in the “Risk Factors” section the risks involved in the investment in this common stock, including but not limited to the following: Risks Related to Our Business •Commercial real estate and commercial loans carry greater credit risk than loans secured by owner occupied one to four family real estate. •The unseasoned nature of our commercial real estate and commercial loan portfolio may result in changes to our estimates of collectability, which may lead to additional provisions or charge offs, which could hurt our profits. •Our commercial and residential construction loans are subject to various lending risks depending on the nature of the borrower’s business, its cash flow and our collateral. •Environmental liability associated with commercial lending could result in losses. •Our business may be adversely affected by credit risks associated with residential property. •The geographic concentration of our loan portfolio and lending activities makes us vulnerable to a downturn in the local economy. •An increase in interest rates or changes in the secondary mortgage market may reduce our mortgage banking revenues, which would negatively impact our non-interest income. •We use significant assumptions and estimates in our financial models to determine the fair value of certain assets, including mortgage servicing rights, origination commitments and loans held for sale. If our assumptions or estimates are incorrect, that may have a negative impact on the fair value of such assets and adversely affect our earnings. •If we are required to repurchase mortgage loans that we have previously sold, it could negatively affect our earnings. •If our allowance for loan losses is not sufficient to cover actual loan losses, our earnings and capital could decrease. •Our portfolio of indirect auto lending and auto lease lending exposes us to increased credit risks. •We depend on our relationship with Credit Union Leasing of America to grow our auto lease loan portfolio. •A portion of our loan portfolio consists of loan participations, which may have a higher risk of loss than loans we originate because we are not the lead lender and we have limited control over credit monitoring. •Changes in interest rates may hurt our results of operations and financial condition. •Hedging against interest rate exposure may adversely affect our earnings. •We may be unable to attract, hire and retain qualified key employees, which could adversely affect our business prospects, including our competitive position and results of operations. •We may not be able to successfully implement our strategic plan. •Failure to attain expected synergies related to the Coastway acquisition could reduce our future earnings per share. •Impairment of goodwill and/or intangible assets could require a charge to earnings, which could adversely affect us. •Our efficiency ratio is high, and we anticipate that it may remain high, as a result of the ongoing implementation of our business strategy. •An increase in FDIC or Co-operative Central Bank insurance assessments could significantly increase our expenses. •The loss of deposits or a change in deposit mix could increase our cost of funding. •Our funding sources may prove insufficient to allow us to meet our obligations, replace depositor withdrawals or support future growth. •Strong competition within our market area could hurt our profits and slow growth. •We are a community bank and our ability to maintain our reputation is critical to the success of our business and the failure to do so may materially adversely affect our performance. •Our banking business is highly regulated, which could limit or restrict our activities and impose financial requirements or limitations on the conduct of our business. •We are subject to capital and liquidity standards that require banks and bank holding companies to maintain more and higher quality capital and greater liquidity than has historically been the case. •We are subject to numerous laws designed to protect consumers, including the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions. •Changes in the valuation of our securities could adversely affect us. •We may need to raise additional capital in the future, but that capital may not be available when it is needed or the cost of that capital may be very high. •We face continuing and growing security risks to our information base, including the information we maintain relating to our customers. •We may not be able to successfully implement future information technology system enhancements, which could adversely affect our business operations and profitability. •We rely on other companies to provide key components of our business infrastructure. •If our risk management framework does not effectively identify or mitigate our risks, we could suffer losses. •Changes in accounting standards could affect reported earnings. •Changes in tax laws and regulations and differences in interpretation of tax laws and regulations may adversely impact our financial statements. •Holders of our subordinated notes have rights that are senior to those of our common shareholders. We have supported a portion of our growth through the issuance of subordinated notes. •Acquisitions may disrupt our business and dilute shareholder value. •Natural disasters, acts of terrorism and other external events could harm our business. Risks Related to the Offering •The future price of the shares of common stock may be less than the $10.00 purchase price per share in the offering. •Our failure to effectively deploy the net proceeds may have an adverse effect on our financial performance. •Our return on equity may be low following the offering. This could negatively affect the trading price of our shares of common stock. •Our stock-based benefit plans will increase our expenses and reduce our income. •The implementation of stock-based benefit plans may dilute your ownership interest. Historically, shareholders have approved these stock-based benefit plans. •Our stock value may be negatively affected by applicable regulations that restrict stock repurchases. •Various factors may make takeover attempts more difficult to achieve. •You may not revoke your decision to purchase New HarborOne common stock in the subscription or community offerings after you send us your order. •The distribution of subscription rights could have adverse income tax consequences. •Securities issued by us, including our common stock, are not FDIC insured. •We are an emerging growth company, and if we elect to comply only with the reduced reporting and disclosure requirements applicable to emerging growth companies, our common stock may be less attractive to investors.
