**EXPLANATORY NOTE**

This registration statement on Form S-8 (the "**Registration Statement**") is being filed by Abpro Holdings, Inc. (f/k/a Atlantic Coastal Acquisition Corp. II) (the "**Registrant**") with the U.S. Securities and Exchange Commission (the "**SEC**") to register the issuance of 6,240,773 shares of common stock, par value $0.0001 per share (the "**Common Stock**") issuable pursuant to the Abpro Holdings, Inc. 2024 Equity Incentive Plan (the "**2024 Plan**"). Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the "**Securities Act**"), this Registration Statement also covers an indeterminate number of additional shares of Common Stock which may be offered and issued to prevent dilution from stock splits, subdivisions, dividends, bonus issues of shares or similar transactions as provided in the 2024 Plan.

On November 13, 2024, the Registrant completed its Business Combination with Abpro Corporation ("**Abpro Corporation**"). In connection with the Business Combination, the Registrant agreed to reserve 10,872,400 shares of Common Stock to be issued pursuant to Rollover Options and Rollover RSUs (each as defined in the Reoffer Prospectus) that were originally issued by Abpro Corporation pursuant to the Abpro Corporation 2014 Stock Incentive Plan (the "**Rollover Shares**"). The Rollover Shares were assumed and will be issued under the 2024 Plan. As of the date of the Registration Statement, there were 6,985,959 shares of Common Stock to be reserved for issuance pursuant to the Rollover Options and Rollover RSUs.

This Registration Statement also includes a prospectus (the "**Reoffer Prospectus**") prepared in accordance with General Instruction C of Form S-8 and in accordance with the requirements of Part I of Form S-3. This Reoffer Prospectus may be used for the reoffer and resale of shares of Common Stock on a continuous or delayed basis that may be deemed to be "control securities" within the meaning of the Securities Act of 1933, as amended (the "**Securities Act**"), and the rules and regulations promulgated thereunder, that are issuable to certain of our executive and other officers and directors identified in the Reoffer Prospectus, and "restricted securities", which are defined for purposes of General Instruction C to Form S-8 as securities issued under any employee benefit plan of the registrant meeting the definition of "restricted securities" in Rule l44(a)(3), whether or not held by affiliates of the registrant, acquired by the selling security holder prior to the filing of the Registration Statement. The number of shares of Common Stock included in the Reoffer Prospectus represents shares of Common Stock issuable to the selling stockholders pursuant to Rollover Options and Rollover RSUs previously granted to the selling stockholders and does not necessarily represent a present intention to sell any or all such shares of Common Stock. The number of shares of Common Stock to be offered or resold by means of the Reoffer Prospectus by the selling stockholders, and any other person with whom any of them is acting in concert for the purpose of selling Common Stock, may not exceed, during any three-month period, the amount specified in Rule 144(e) under the Securities Act.

**Reoffer Prospectus**

**Abpro Holdings, Inc.**

**6,985,959 shares of Common Stock**

This reoffer prospectus relates to 6,985,959 shares (the "**Shares**") of common stock, par value $0.0001 per share (the "**Common Stock**") of Abpro Holdings, Inc. ("**New Abpro**," the "**Company**" or the "**Registrant**"), which may be offered from time to time by certain stockholders that are current or former employees, consultants, and advisors of the Registrant (the "**Selling Stockholders**") for their own accounts. We will not receive any of the proceeds from the sale of Shares by the Selling Stockholders made hereunder. The Shares were or will be acquired upon the exercise of stock options (the "**Rollover Options**") and restricted stock units (the "**Rollover RSUs**") assumed by the Company in connection with the Company's Business Combination with Abpro Corporation ("**Abpro Corporation**") and were originally issued by Abpro Corporation pursuant to the Abpro Corporation 2014 Stock Incentive Plan.

The Selling Stockholders may sell the securities described in this reoffer prospectus in a number of different ways and at varying prices, including sales in the open market, sales in negotiated transactions and sales by a combination of these methods. The Selling Stockholders may sell any, all or none of the Shares and we do not know when or in what amount the Selling Stockholders may sell their Shares hereunder following the effective date of this Registration Statement. The price at which any of the Shares may be sold, and the commissions, if any, paid in connection with any such sale, are unknown and may vary from transaction to transaction. The Shares may be sold at the market price of the Common Stock at the time of a sale, at prices relating to the market price over a period of time, or at prices negotiated with the buyers of Shares. The Shares may be sold through underwriters or dealers which the Selling Stockholders may select. If underwriters or dealers are used to sell the Shares, we will name them and describe their compensation in a prospectus supplement. We provide more information about how the Selling Stockholders may sell their Shares in the section titled "Plan of Distribution." The Selling Stockholders will bear all sales commissions and similar expenses. Any other expenses incurred by us in connection with the registration and offering that are not borne by the Selling Stockholders will be borne by us.

Our Common Stock and our public warrants are listed on the Nasdaq Global Market ("**Nasdaq**") under the symbols "ABP" and "ABPWW," respectively. On June 17, 2025, the closing price of our Common Stock was $0.22 and the closing price for our public warrants was $0.02.

The amount of securities to be offered or resold under this reoffer prospectus by each Selling Stockholder or other person with whom he or she is acting in concert for the purpose of selling our securities, may not exceed, during any three month period, the amount specified in Rule 144(e) under the Securities Act of 1933, as amended (the "**Securities Act**").

**We are an "emerging growth company" as defined under the federal securities laws and, as such, have elected to comply with certain reduced public company reporting requirements.**

**Investing in our securities involves a high degree of risk. Before buying any securities, you should carefully read the discussion of the risks of investing in our securities in "Risk Factors" beginning on page 6 of this reoffer prospectus.**

The Securities and Exchange Commission (the "**SEC**") may take the view that, under certain circumstances, the Selling Stockholders and any broker-dealers or agents that participate with the Selling Stockholders in the distribution of the Shares may be deemed to be "underwriters" within the meaning of the Securities Act. Commissions, discounts or concessions received by any such broker-dealer or agent may be deemed to be underwriting commissions under the Securities Act. See the section titled "Plan of Distribution."

**Neither the SEC nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this reoffer prospectus. Any representation to the contrary is a criminal offense.**

The date of this prospectus is June 18, 2025

**The Company**

New Abpro is a biotechnology company dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and life-threatening diseases. New Abpro is focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging its proprietary DiversImmune® and MultiMab<sup>TM</sup> antibody discovery and engineering platforms, New Abpro is developing a pipeline of next-generation antibodies, both independently and through collaborations with global pharmaceutical and research institutions.

**The Background**

On November 13, 2024, to Atlantic Coastal Acquisition Corp. II ("**ACAB**") completed a series of transactions that resulted in the combination (the "**Business Combination**") of ACAB with Abpro Corporation pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated September 4, 2024 (the "**BCA**"), by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of ACAB ("**Merger Sub**"), and Abpro Corporation (the "**Closing**"), following the approval at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "**Special Meeting**"). On November 12, 2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement, which was filed with the U.S. Securities and Exchange Commission (the "**SEC**") on October 18, 2024 (the "**Proxy Statement/Prospectus**"), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of Common Stock, consisting of 39,123,200 shares of Common Stock issued to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance in connection with certain Abpro Corporation Rollover RSUs and Rollover Options (collectively, the "**Merger Consideration**"). In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors in connection with the PIPE Financing, an aggregate of 1,282,852 shares to various vendors in connection with the closing of the Business Combination (the "**Closing**"), and Atlantic Coastal Acquisition Management II LLC forfeited and New Abpro cancelled 966,442 shares of Common Stock.

Simultaneous with the Closing, New Abpro also completed its previously announced private investment in public equity, issuing 1,122,467 shares of Common Stock and 2,244,934 Incentive Shares, which raised $7.0 million in gross proceeds.

Our Common Stock and our public warrants are listed on the Nasdaq Global Market ("**Nasdaq**") under the symbols "ABP" and "ABPWW," respectively. On June 17, 2025, the closing price of our Common Stock was $0.22 and the closing price for our public warrants was $0.02.

The rights of holders of our Common Stock and warrants are governed by our second amended and restated certificate of incorporation (the "Charter") and our amended and restated bylaws (the "**Bylaws**") and the General Corporation Law of the State of Delaware (the "**DGCL**"), and in the case of the public warrants, the Public Warrant Agreement, dated January 13, 2022, by and between ACAB and Continental Stock Transfer & Trust Company (the "**Public Warrant Agreement**") and the Private Warrant Agreement, dated January 13, 2022, by and between ACAB and Continental Stock Transfer & Trust Company (the "**Private Warrant Agreement**" and, together with the Public Warrant Agreement, the "**Warrant Agreements**").

**Implications of Being an Emerging Growth Company**

We are an "emerging growth company" as defined in Section 2(a) of the Securities Act of 1933, as amended (the "**Securities Act**"), as modified by the Jumpstart Our Business Startups Act of 2012 (the "**JOBS Act**"). As an emerging growth company, we may benefit from specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

● presentation of only two years of audited financial statements and only two years of related management's discussion and analysis of financial condition and results of operations in this reoffer prospectus;

● reduced disclosure about our executive compensation arrangements;

● no non-binding stockholder advisory votes on executive compensation or golden parachute arrangements;

● exemption from any requirement of the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements (i.e., an auditor discussion and analysis); and

● exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may benefit from these exemptions until we cease to be an emerging growth company. We will cease to be an emerging growth company upon the earliest of: (a) the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion or more; (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of the ACAB initial public offering; (c) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (d) the date on which we are deemed to be a "large accelerated" filer under the Securities Exchange Act of 1934, as amended (the "**Exchange Act**"). We may choose to benefit from some but not all of these reduced disclosure obligations in future filings. If we do, the information that we provide stockholders may be different than you might get from other public companies in which you hold stock.

**Summary Risk Factors**

You should consider all the information contained in this reoffer prospectus before making a decision to invest in our Common Stock. Below please find a summary of the principal risks we face, organized under relevant headings. These risks are discussed more fully under Part I, Item 1A, "Risk Factors," included in our Annual Report on Form 10-K, filed with the SEC on April 15, 2025 (the "**Annual Report**"):

*Risks Related to Our Business and Industry*

● Our management has concluded that uncertainties around our ability to raise additional capital raise substantial doubt about our ability to continue as a going concern, including drug development;

● Drug development is a highly uncertain undertaking and involves a substantial degree of risk;

● Our product candidates are in early stages of development and have never been tested in a human subject;

● The market may not be receptive to our product candidates based on our novel therapeutic modality, and we may not generate any revenue from the sale or licensing of product candidates;

● We will need substantial additional funds to advance development of our product candidates, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or future product candidates;

● Through our AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune Limited, or MedImmune (now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca;

● We have entered, and may in the future seek to enter, into collaborations with third parties for the development and commercialization of our product candidates. If such collaborations are not successful, we may not be able to capitalize on the market potential of our product candidates;

● If our partners cease development efforts under our existing or future collaborations, or if any of those agreements is terminated, these collaborations may fail to lead to commercial products, and we may never receive milestone payments or future royalties under these agreements;

● If third parties on which we intend to rely on to conduct certain preclinical studies, or any future clinical trials, do not perform as contractually required, fail to satisfy regulatory or legal requirements or miss expected deadlines, our development program could be delayed with material and adverse effects on our business, financial condition, results of operations and prospects;

● Because we may rely on third-party manufacturing and supply partners for preclinical and clinical development materials, our supply may become limited or interrupted or may not be of satisfactory quantity or quality;

● We face competition from entities that have developed or may develop product candidates for the treatment of the diseases that we are initially targeting, including companies developing novel treatments and technology platforms;

● Any inability to attract and retain qualified key management, technical personnel and employees would impair our ability to implement our business plan; and

● Litigation and legal proceedings may substantially increase our costs and harm our business.

*Risks Related to Intellectual Property*

● If we are unable to obtain or protect intellectual property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate, we may not be able to compete effectively;

● If we fail to comply with our obligations under any license, collaboration or other intellectual property related agreements, we may be required to pay damages and could lose intellectual property rights that are necessary for developing, commercializing and protecting our current or future technologies or product candidates or we could lose certain rights to grant sublicenses;

● Patent terms may be inadequate to protect our competitive position on our current or future technologies or product candidates for an adequate amount of time;

● We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business; and

● If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

*Risks Related to Government Regulation*

● Clinical development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results;

● We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our product candidates, resulting in substantial harm to our business;

● We may in the future conduct clinical trials for current or future product candidates outside the United States, and the FDA and comparable foreign regulatory authorities may not accept data from such trials;

● Even if we receive regulatory approval for any of our product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products;

● Healthcare legislative reform measures may have a material adverse effect on our business and results of operations;

● If we or existing or future partners, manufacturers or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could affect our ability to develop, market and sell our products and may harm our reputation; and

● We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.

*Risks Related to Our Organization and Structure*

● The Charter and the Bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees;

● Anti-takeover provisions in our governing documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our Common Stock;

● New Abpro's management team may not successfully or efficiently manage its transition to being a public company;

● We have identified material weaknesses in our internal control over financial reporting, which could affect our ability to ensure timely and reliable financial reports and weaken investor confidence in our financial reporting;

● The restatement of prior period financial statements may affect investor confidence and raise reputational issues; and

● New Abpro is an "emerging growth company," and its reduced SEC reporting requirements may make its shares less attractive to investors.

*Risks Related to an Investment in Our Securities*

● An active market for New Abpro's securities may not develop, which would adversely affect the liquidity and price of New Abpro's securities;

● Our failure to meet Nasdaq's continued listing requirements could result in a delisting of New Abpro's Common Stock and Public Warrants;

● The market price for our Common Stock may decline;

● The Common Stock price may fluctuate, and you could lose all or part of your investment as a result;

● New Abpro stockholders may experience dilution in the future;

● There is no guarantee that the Warrants will ever be in the money; they may expire worthless, or the terms of Warrants may be amended;

● There may be sales of a substantial amount of our Common Stock by current stockholders, and these sales could cause the price of our Common Stock to fall; and

● It is not possible to predict the actual number of shares we will sell under the SEPA, or the actual gross proceeds resulting from those sales. Further, we may not have access to any or the full amount available under the SEPA.

**Corporate Information**

New Abpro's principal executive offices are located at 68 Cummings Park Drive, Woburn, MA 01801, and New Abpro's telephone number is 1-800-396-5890.

**RISK FACTORS**

An investment in our securities involves a high degree of risk. You should carefully read and review the risk factors discussed under the caption "Risk Factors" in our Annual Report, the risk factors discussed under the caption "Risk Factors" in any accompanying prospectus supplement, and any risk factors discussed in our other filings with the SEC which are incorporated by reference into this reoffer prospectus and any accompanying prospectus supplement before investing in our securities. These risks and uncertainties are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us, or that we currently view as immaterial, may also materially and adversely affect us. If any of the risks or uncertainties described in our Annual Report, any accompanying prospectus supplement or our other filings with the SEC or if any additional risks and uncertainties actually occur, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that case, the trading price of our securities could decline, and you could lose all or part of your investment.

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This reoffer prospectus, and any documents we incorporate by reference, contain certain forward-looking statements that involve substantial risks and uncertainties. All statements contained in this reoffer prospectus and any documents we incorporate by reference, other than statements of historical facts, are forward-looking statements including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans, objectives of management and expected market growth. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Forward-looking statements appear in a number of places in this reoffer prospectus and the documents incorporated by reference herein, including, without limitation, in the section titled "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Risk Factors" and "Our Business." In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as "plan," "believe," "expect," "anticipate," "intend," "outlook," "estimate," "forecast," "project," "continue," "could," "may," "might," "possible," "potential," "predict," "should," "would" and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements are based on the current expectations of the management of New Abpro and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. There can be no assurance that future developments will be those that have been anticipated.

All subsequent written and oral forward-looking statements concerning matters addressed in this reoffer prospectus and attributable to New Abpro or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this reoffer prospectus. Except to the extent required by applicable law or regulation, New Abpro undertakes no obligation to update these forward-looking statements to reflect events or circumstances after the date of this reoffer prospectus or to reflect the occurrence of unanticipated events.

**SELLING STOCKHOLDERS**

This reoffer prospectus relates to the resale by the Selling Stockholders from time to time of up to an aggregate of 6,985,959 shares of Common Stock underlying Rollover Options and Rollover RSUs that were assumed by the Company in connection with the Business Combination. The Selling Stockholders may from time to time offer and sell any or all of the shares of Common Stock set forth below pursuant to this reoffer prospectus and any accompanying prospectus supplement.

In particular, the Selling Stockholders identified below may have sold, transferred or otherwise disposed of all or a portion of their securities after the date on which they provided us with information regarding their securities in transactions exempt from registration under the Securities Act.

The following table sets forth certain information provided by or on behalf of the Selling Stockholders concerning the Shares that may be offered from time to time by each Selling Stockholder with this reoffer prospectus.

**PLAN OF DISTRIBUTION**

We are registering for resale by the Selling Stockholders from time to time up to 6,985,959 shares of Common Stock underlying Rollover Options and Rollover RSUs that were assumed by the Company in connection with the Business Combination. We will not receive any proceeds from the sale of the Shares by the Selling Stockholders. The aggregate proceeds to the Selling Stockholders will be the purchase price of the securities less any discounts and commissions borne by the Selling Stockholders.

The Selling Stockholders will pay any underwriting discounts and commissions and expenses incurred by the Selling Stockholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Stockholders in disposing of the securities. We are required to pay all other fees and expenses incident to the registration of the Shares to be offered and sold pursuant to this reoffer prospectus.

The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. Each Selling Stockholder reserves the right to accept and, together with its respective agents, to reject, any proposed purchase of securities to be made directly or through agents. The Selling Stockholders and any of their permitted transferees may sell their securities offered by this reoffer prospectus on any stock exchange, market or trading facility on which the securities are traded or in private transactions. If underwriters are used in the sale, such underwriters will acquire the shares for their own account. These sales may be at a fixed price or varying prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices. The securities may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the securities will be subject to certain conditions.

The Selling Stockholders may sell their shares by one or more of, or a combination of, the following methods:

● purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this reoffer prospectus;

● ordinary brokerage transactions and transactions in which the broker solicits purchasers;

● block trades in which the broker-dealer so engaged will attempt to sell the offered securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

● an over-the-counter distribution in accordance with the rules of Nasdaq;

● through trading plans entered into by a Selling Stockholder pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the "**Exchange Act** "), that are in place at the time of an offering pursuant to this reoffer prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

● through the distribution of the securities by any Selling Stockholder to its partners, members or stockholders

● through one or more underwritten offerings on a firm commitment or best efforts basis;

● settlement of short sales entered into after the effective date the registration statement of which this reoffer prospectus is a part;

● agreements with broker-dealers to sell a specified number of the securities at a stipulated price per share or warrant;

● in "at the market" offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

● in privately negotiated transactions;

● in options transactions;

● through a combination of any of the above methods of sale; or

● any other method permitted pursuant to applicable law.

There can be no assurance that the Selling Stockholders will sell all or any of the securities offered by this reoffer prospectus. In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this reoffer prospectus. The Selling Stockholders have the sole and absolute discretion not to accept any purchase offer or make any sale of securities if they deem the purchase price to be unsatisfactory at any particular time.

The Selling Stockholders and any other person participating in the sale of the Shares will be subject to the Exchange Act rules including, without limitation, Regulation M, which may limit the timing of purchases and sales of any of the Shares by the Selling Stockholders and any other person. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the Shares to engage in market-making activities with respect to the particular Shares being distributed. This may affect the marketability of the Shares and the ability of any person or entity to engage in market-making activities with respect to the Shares.

The Selling Stockholders may indemnify any broker or underwriter that participates in transactions involving the sale of the Shares against certain liabilities, including liabilities arising under the Securities Act.

**Item 4. Description of Securities.**

Not applicable.

**Item 5. Interests of Named Experts and Counsel.**

Not applicable.

**Item 6. Indemnification of Directors and Officers.**

Section 145 of the DGCL provides, generally, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided that a court shall have determined, upon application, that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

In accordance with Section 102(b)(7) of the DGCL, the Charter provides that a director will not be personally liable to the Registrant or the Registrant's stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Registrant or the Registrant's stockholders, (ii) for acts of bad faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision became effective. Accordingly, these provisions will have no effect on the availability of equitable remedies such as an injunction or rescission based on a director's breach of his or her duty of care.

The Charter provides that the Registrant will indemnify its present and former directors and officers to the fullest extent permitted by the DGCL and that such indemnification will not be exclusive of any other rights to which those seeking indemnification may have or hereafter acquire under law, the charter, the Bylaws, an agreement, a vote of stockholders or disinterested directors, or otherwise.

The Registrant has entered into indemnification agreements with each of its current directors and executive officers. These agreements require the Registrant to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to the Registrant, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. The Registrant also intends to enter into indemnification agreements with future directors and executive officers.

**Item 7. Exemption from Registration Claimed.**

Not applicable.

 **Item 8. Exhibits.**

The exhibits required to be filed as part of this registration statement are listed in the Exhibit Index set forth below immediately preceding the signature page to this registration statement.

**Item 9. Undertakings.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; *provided*, *however*, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.1 Pursuant to the Plan, the Company hereby grants to the Grantee on the Grant Date an Award consisting of, in the aggregate, [__] Restricted Stock Units ("Restricted Stock Units"). Each Restricted Stock Unit represents the right to receive one share of Common Stock, subject to the terms and conditions set forth in this Agreement and the Plan. Capitalized terms that are used but not defined herein have the meaning ascribed to them in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.2 The Restricted Stock Units shall be credited to a separate account maintained for the Grantee on the books and records of the Company ("Account"). All amounts credited to the Account shall continue for all purposes to be part of the general assets of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>2.</u> <u>Consideration</u>. The grant of the Restricted Stock Units is made in consideration of the services to be rendered by the Grantee to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>3.</u> <u>Vesting</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1 Except as otherwise provided herein, provided that the Grantee remains in continuous employment or other service ("Continuous Service") with the Company through the applicable vesting date, the Restricted Stock Units will vest in accordance with the following schedule (the period during which restrictions apply, the "Restricted Period"):

**Vesting Start Date:** [__]

**Vesting Schedule:** [*Insert vesting schedule*]. All vesting shall cease upon the date of termination of employment or provision of services to the Company. Once vested, the Restricted Stock Units become "Vested Units."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 If the Grantee's Continuous Service terminates for any reason at any time before all of the Restricted Stock Units have vested, the Grantee's unvested Restricted Stock Units shall be automatically forfeited upon such termination of Continuous Service and the Company shall not have any further obligations to the Grantee under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>4.</u> <u>Restrictions</u>. Subject to any exceptions set forth in this Agreement or the Plan, during the Restricted Period and until such time as the Restricted Stock Units are settled in accordance with Section 6, the Restricted Stock Units or the rights relating thereto may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Grantee. Any attempt to assign, alienate, pledge, attach, sell or otherwise transfer or encumber the Restricted Stock Units or the rights relating thereto shall be wholly ineffective and, if any such attempt is made, the Restricted Stock Units will be forfeited by the Grantee and all of the Grantee's rights to such units shall immediately terminate without any payment or consideration by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>5.</u> <u>Rights as Shareholder; Dividend Equivalents</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1 The Grantee shall not have any rights of a shareholder with respect to the shares of Common Stock underlying the Restricted Stock Units unless and until the Restricted Stock Units vest and are settled by the issuance of such shares of Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2 Upon and following the settlement of the Restricted Stock Units, the Grantee shall be the record owner of the shares of Common Stock underlying the Restricted Stock Units unless and until such shares are sold or otherwise disposed of, and as record owner shall be entitled to all rights of a shareholder of the Company (including voting rights).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3 The Grantee shall not be entitled to any dividends or dividend equivalents with respect to the Restricted Stock Units to reflect any dividends payable on shares of Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>6.</u> <u>Settlement of Restricted Stock Units</u>. Subject to Section 9 hereof, promptly following the vesting date, and in any event no later than March 15 of the calendar year following the calendar year in which such vesting occurs, the Company shall (a) issue and deliver to the Grantee the number of shares of Common Stock equal to the number of Vested Units; and (b) enter the Grantee's name on the books of the Company as the shareholder of record with respect to the shares of Common Stock delivered to the Grantee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>7.</u> <u>No Right to Continued Service</u>. Neither the Plan nor this Agreement shall confer upon the Grantee any right to be retained in any position, as an employee, consultant or director of the Company. Further, nothing in the Plan or this Agreement shall be construed to limit the discretion of the Company to terminate the Grantee's Continuous Service at any time, with or without Cause.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>8.</u> <u>Adjustments</u>. If any change is made to the outstanding Common Stock or the capital structure of the Company, if required, the Restricted Stock Units shall be adjusted or terminated in any manner as contemplated by the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>9.</u> <u>Tax Liability and Withholding</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.1 The Grantee shall be required to pay to the Company, and the Company shall have the right to deduct from any compensation paid to the Grantee pursuant to the Plan or otherwise, the amount of any required withholding taxes in respect of the Restricted Stock Units and to take all such other action as the Board deems necessary to satisfy all obligations for the payment of such withholding taxes. The Board may permit the Grantee to satisfy any federal, state or local tax withholding obligation by any of the following means, or by a combination of such means: (i) tendering a cash payment; (ii) withholding from any compensation otherwise payable to the Grantee by the Company or an affiliate; (iii) subject to the approval of the independent members of the Board, authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable or deliverable to the Grantee as a result of the vesting of the Restricted Stock Units; provided, however, that no shares of Common Stock shall be withheld with a value exceeding the minimum amount of tax required to be withheld by law; (iv) delivering to the Company previously owned and unencumbered shares of Common Stock or (v) permitting or requiring the Grantee to enter into a "same day sale" commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a "FINRA Dealer") whereby the Grantee irrevocably elects to sell a portion of the shares to be delivered in connection with the Restricted Stock Units to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its affiliates;.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.2 Notwithstanding any action the Company takes with respect to any or all income tax, social insurance, payroll tax, or other tax-related withholding ("Tax-Related Items"), the ultimate liability for all Tax-Related Items is and remains the Grantee's responsibility and the Company (a) makes no representation or undertakings regarding the treatment of any Tax-Related Items in connection with the grant, vesting or settlement of the Restricted Stock Units or the subsequent sale of any shares; and (b) does not commit to structure the Restricted Stock Units to reduce or eliminate the Grantee's liability for Tax-Related Items. Unless the Tax-Related Items are satisfied by the Grantee, the Company will have no obligation to deliver to the Grantee any Common Stock. If the Company's obligation to withhold arises prior to the delivery to the Grantee of Common Stock or it is determined after the delivery of Common Stock to the Grantee that the amount of the Company's withholding obligation was greater than the amount withheld by the Company, the Grantee agrees to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>10.</u> <u>Compliance with Law</u>. The issuance and transfer of shares of Common Stock shall be subject to compliance by the Company and the Grantee with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Company's shares of Common Stock may be listed. No shares of Common Stock shall be issued or transferred unless and until any then applicable requirements of state and federal laws and regulatory agencies have been fully complied with to the satisfaction of the Company and its counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>11.</u> <u>Notices</u>. Any notice required to be delivered to the Company under this Agreement shall be in writing and addressed to the Secretary of the Company at the Company's principal corporate offices. Any notice required to be delivered to the Grantee under this Agreement shall be in writing and addressed to the Grantee at the Grantee's address as shown in the records of the Company. Either party may designate another address in writing (or by such other method approved by the Company) from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>12.</u> <u>Governing Law</u>. This Agreement will be construed and interpreted in accordance with the laws of the Commonwealth of Massachusetts, without giving effect to principles of conflicts of laws, and construed accordingly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>13.</u> <u>Interpretation</u>. Any dispute regarding the interpretation of this Agreement shall be submitted by the Grantee or the Company to the Board for review. The resolution of such dispute by the Board shall be final and binding on the Grantee and the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>14.</u> <u>Restricted Stock Units Subject to Plan</u>. This Agreement is subject to the Plan as approved by the Company's shareholders. The terms and provisions of the Plan as it may be amended from time to time are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>15.</u> <u>Successors and Assigns</u>. The Company may assign any of its rights under this Agreement. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this Agreement will be binding upon the Grantee and the Grantee's beneficiaries, executors, administrators and the person(s) to whom the Restricted Stock Units may be transferred by will or the laws of descent or distribution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>16.</u> <u>Severability</u>. The invalidity or unenforceability of any provision of the Plan or this Agreement shall not affect the validity or enforceability of any other provision of the Plan or this Agreement, and each provision of the Plan and this Agreement shall be severable and enforceable to the extent permitted by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>17.</u> <u>No Contractual Right</u>. The grant of the Restricted Stock Units in this Agreement does not create any contractual right or other right to receive any Restricted Stock Units or other Awards in the future. Future Awards, if any, will be at the sole discretion of the Company. Any amendment, modification, or termination of the Plan shall not constitute a change or impairment of the terms and conditions of the Grantee's employment with the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>18.</u> <u>Amendment</u>. The Board has the right to amend, alter, suspend, discontinue or cancel the Restricted Stock Units, prospectively or retroactively; provided that, any amendments that are deemed by the Board to be materially adverse to the Grantee and are not required as a matter of law may be made only with the Grantee's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>19.</u> <u>Section 409A</u>. This Agreement is intended to comply with Section 409A of the Code or an exemption thereunder and shall be construed and interpreted in a manner that is consistent with the requirements for avoiding additional taxes or penalties under Section 409A of the Code. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this Agreement comply with Section 409A of the Code and in no event shall the Company be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Grantee on account of non-compliance with Section 409A of the Code. If the Grantee is deemed a "specified employee" within the meaning of Section 409A of the Code, as determined by the Board, at a time when the Grantee becomes eligible for settlement of the Restricted Stock Units upon his "separation from service" within the meaning of Section 409A of the Code, then to the extent necessary to prevent any accelerated or additional tax under Section 409A of the Code, such settlement will be delayed until the earlier of: (a) the date that is six months following the Grantee's separation from service and (b) the Grantee's death. Each installment of shares that vests is a "separate payment" for purposes of Treasury Regulation Section 1.409A-2(b)(2).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>20.</u> <u>No Impact on Other Benefits</u>. The value of the Grantee's Restricted Stock Units is not part of his or her normal or expected compensation for purposes of calculating any severance, retirement, welfare, insurance or similar employee benefit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>21.</u> <u>Unsecured Obligation</u>. The Grantee's award is unfunded, and as a holder of vested Restricted Stock Units, Grantee will be considered an unsecured creditor of the Company with respect to the Company's obligation, if any, to issue shares or other property pursuant to this Agreement. Grantee will not have voting or any other rights as a stockholder of the Company with respect to the shares to be issued pursuant to this Agreement until such shares are issued to Grantee. Upon such issuance, Grantee will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between Grantee and the Company or any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>22.</u> <u>Lock-Up Period</u>. Grantee agrees that following receipt of the Common Stock underlying the Restricted Stock Units, Grantee will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by Grantee, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2711 or NYSE Member Rule 472 and similar rules and regulations (the "Lock-Up Period"); provided, however, that nothing contained in this Section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. Grantee also agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. To enforce the foregoing covenant, the Company may impose stop-transfer instructions on Grantee's shares of Common Stock until the end of the Lock-Up Period. The underwriters of the Company's stock are intended third-party beneficiaries of this Section and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>23.</u> <u>Counterparts</u>. This Agreement may be executed in counterparts, each of which shall be deemed an original but all of which together will constitute one and the same instrument. Counterpart signature pages to this Agreement transmitted by facsimile transmission, by electronic mail in portable document format (.pdf), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing an original signature.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>24.</u> <u>Acceptance</u>. The Grantee hereby acknowledges receipt of a copy of the Plan and this Agreement. The Grantee has read and understands the terms and provisions thereof, and accepts the Restricted Stock Units subject to all of the terms and conditions of the Plan and this Agreement. The Grantee acknowledges that there may be adverse tax consequences upon the vesting or settlement of the Restricted Stock Units or disposition of the underlying shares and that the Grantee has been advised to consult a tax advisor prior to such vesting, settlement or disposition.

● with the consent of the Company, any of the other methods set forth in the Plan.

As an additional condition to exercise of this Option, the Holder shall deliver to the Company an investment letter in form and substance satisfactory to the Company and its counsel. No such investment letter shall be required as a condition to such exercise at any time when there shall be an effective registration statement under the Securities Act of 1933, as amended (the '·<u>Act</u>") covering the shares for which this Option may be exercised.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.** **Expiration Date of Option:** Tenth anniversary of Date of Grant

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.** **Vesting Schedule:** This Option shall become exercisable for 25% of the maximum number of shares
granted on the first anniversary of the Vesting Start Date and the remaining 75% of the maximum number of shares granted shall become
exercisable in 36 equal monthly installments over the three year period following the first anniversary of the Vesting Start Date (in
each case rounded down to the nearest whole share, except for the last vesting installment). All vesting shall cease upon the date of
termination of employment or provision of services to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9.** **Termination of Employment.** This Option shall terminate on the earliest to occur of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. the date of expiration hereof;

of services to, the Company by the Company for Cause (as defined in the Plan);

provision of services to, the Company by the Company without Cause (other than for death or permanent disability as defined in the Plan).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.** **Company's Right of First Refusal.** Prior to the effective date of a registration statement
under the Act, any shares of stock issued pursuant to exercise of this Option shall be subject to the Company's right of first refusal
as set forth at <u>Appendix A</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11.** **Lock-Up Agreement.** The Holder agrees that upon the request of the Company or the managing
 underwriter(s) of any offering of securities of the Company that is the subject of a registration statement filed under the Act, for

 enable the underwriter(s) of such offering to comply with Rule 271 l (f) of the Financial Industry Regulatory Authority or any
 amendment or successor thereto) from the effective date of the registration statement under the Act for such offering, the Holder
 will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any shares of Common
 Stock issued pursuant to the exercise of this Option, without the prior written consent of the Company and such underwriters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**12.** f[Incentive Stock Option: **Incentive Stock Option; Disqualifying Disposition**. Although this Option is intended to qualify as an incentive stock option under the Internal
Revenue Code of 1986 (the "Code"), the Company makes no representation as to the tax treatment upon exercise of this Option
or sale or other disposition of the shares covered by this Option, and the Holder is advised to consult a personal tax advisor. Upon a
Disqualifying Disposition of shares received upon exercise of this Option, the Holder will forfeit the favorable income tax treatment
otherwise available with respect to the exercise of this Option. A "Disqualifying Disposition" shall have the meaning specified
in Section 421(b) of the Code; as of the date of grant of this Option a Disqualifying Disposition is any disposition (including any sale)

date on which the Holder acquired such shares by exercising this Option, provided that such holding period requirements terminate upon
the death of the Holder. The Holder shall notify the Company in writing immediately upon making a Disqualifying Disposition of any shares
of Common Stock received pursuant to the exercise of this Option, and shall provide the Company with any information that the Company
shall request concerning any such Disqualifying Disposition.]

[Non-Statutory Stock Option: **Tax Withholding.** The Company's obligation to deliver shares shall be subject to the Holder's satisfaction of any applicable federal, state and local income and employment tax withholding requirements.]

to the Company and delivered to the office of the Company, Abpro Corporation, 65 Cummings Park Dr., Woburn, MA 01801, attention of the
President, or such other address as the Company may hereafter designate.

Any notice to be given to the Holder hereunder shall be deemed sufficient if addressed to and delivered in person to the Holder at his or her address furnished to the Company or when deposited in the mail, postage prepaid, addressed to the Holder at such address.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**14.** **Survival of Provisions.** Sections 10, 11 and <u>Appendix A</u> shall survive the termination, expiration
or exercise of this Option, as shall any other provisions which, by their terms, apply beyond the term of this Option.

**APPENDIX A**

Right of First Refusal

&nbsp;&nbsp;&nbsp;&nbsp;1. General. Prior to the effective date of a registration statement under the Securities Act of 1933, as
amended (the "Act"), covering any shares of the Company's Common Stock and until such time as the Company shall have
effected a public offering of its Common Stock registered under the Act, in the event that, at any time when the Holder (which term for
purposes of this section shall mean the Holder and his or her executors, administrators and any other person to whom this Option may be
transferred by will or the laws of descent and distribution) is permitted to do so, the Holder desires to sell, assign or otherwise transfer
any of the shares issued upon the exercise of this Option, the Holder shall first offer such shares to the Company by giving written notice
of the Holder's desire so to sell, assign or transfer such shares.

&nbsp;&nbsp;&nbsp;&nbsp;2. Notice of Intended Transfer. The notice shall state the number of shares offered, the name of the person
or persons to whom it is proposed to sell, assign or transfer such shares and the price at which such shares are intended to be sold,
assigned or transferred. Such notice shall constitute an offer to the Company for the Company to purchase the number of shares set forth
in the notice at a price per share equal to the price stated therein.

&nbsp;&nbsp;&nbsp;&nbsp;3. Company to Accept or Decline Within 30 Days. The Company may accept the offer as to all, but not less
than all, such shares by notifying the Holder in writing within 30 days after receipt of such notice of its acceptance of the offer. If
the offer is accepted, the Company shall have 60 days after such acceptance within which to purchase the offered shares at a price per
share as aforesaid. If within the applicable time periods the Holder does not receive notice of the Company's intention to purchase
the offered shares, or if payment in full of the purchase price is not made by the Company, the offer shall be deemed to have been rejected
and the Holder may transfer title to such shares within 90 days from the date of the Holder's written notice to the Company of the
Holder's intention to sell, but such transfer shall be made only to the proposed transferee and at the proposed price as stated
in such notice and after compliance with any other provisions of this Option applicable to the transfer of such shares.

&nbsp;&nbsp;&nbsp;&nbsp;4. Transferred Shares to Remain Subject to Right of First Refusal. Shares that are so transferred to such
transferee shall remain subject to the rights of the Company set forth in this Appendix A. As a condition to such transfer, such transferee
shall execute and deliver all such documents as the Company may require to evidence the binding agreement of such transferee so to remain
subject to the rights of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;5. Remedies of Company. No sale, assignment, pledge or other transfer of any of the shares covered by this
Option shall be effective or given effect on the books of the Company unless all of the applicable provisions of this Appendix A have
been duly complied with, and the Company may inscribe on the face of any certificate representing any of such shares a legend referring
to the provisions of this Appendix A. If any transfer of shares is made or attempted in violation of the foregoing restrictions, or if
shares are not offered to the Company as required hereby, the Company shall have the right to purchase such shares from the owner thereof
or his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which
it may have, the Company may enforce its rights by actions for specific performance (to the extent permitted by law) and may refuse to
recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and voting
rights, until all applicable provisions hereof have been complied with.

&nbsp;&nbsp;&nbsp;&nbsp;6. Shares Subject to Right of First Refusal. For purposes of the Right of First Refusal pursuant to this
Appendix A, the term "shares" shall mean any and all new, substituted or additional securities or other property issued to
the Holder, by reason of his or her ownership of Common Stock pursuant to the exercise of this Option, in connection with any stock dividend,
liquidating dividend, stock split or other change in the character or amount of any of the outstanding securities of the Company, or any
consolidation, merger or sale of all or substantially all of the assets of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;7. Legends on Stock Certificates. Any certificate representing shares of stock subject to the provisions
of this Appendix A may have endorsed thereon one or more legends, substantially as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. "Any disposition of any interest in the securities represented by this certificate is subject to restrictions, and the securities represented by this certificate are subject to certain options, contained in a certain agreement between the record holder hereof and the Company, a copy of which will be mailed to any holder of this certificate without charge upon receipt by the Company of a written request therefor."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. "The shares of stock represented by this certificate have not been registered under the Securities Act of 1933 or under the securities laws of any state and may not be pledged, hypothecated, sold or otherwise transferred unless such shares have been registered under the Act or unless the Company has received an opinion of counsel satisfactory to the Company, in form and substance satisfactory to the Company, that such registration is not required."

&nbsp;&nbsp;&nbsp;&nbsp;8. Right of First Refusal to Lapse Upon Registration. The restrictions imposed by this Appendix A shall terminate
in all respects upon the effective date of a registration statement under the Act covering any of the Company's Common Stock.

**2024 EQUITY INCENTIVE PLAN**

**RESTRICTED STOCK UNIT AGREEMENT**

**ABPRO HOLDINGS, INC.**

**2024 EQUITY INCENTIVE PLAN**

**<u>RESTRICTED STOCK UNIT AGREEMENT</u>**

Pursuant to Participant's Restricted Stock Unit Grant Notice (the "***Grant Notice***") and this Restricted Stock Unit Agreement (this "***Agreement***"), Abpro Holdings, Inc., a Delaware corporation (the "***Company***") has granted Participant the number of RSUs under the Abpro Holdings, Inc. 2024 Equity Incentive Plan (the "***Plan***") indicated in Participant's Grant Notice, each of which represents the right to receive one Common Share. The RSUs are granted to Participant effective as of the date of grant set forth in the Grant Notice (the "***Date of Grant***"). If there is any conflict between the terms in the Grant Notice, **<u>Exhibit A</u>** to the Grant Notice, this Agreement and the Plan, then such conflict shall be resolved by giving such documents precedence in the following order: **<u>Exhibit A</u>**, the Grant Notice, this Agreement then the Plan. Capitalized terms not explicitly defined in this Agreement or in the Grant Notice but defined in the Plan will have the same definitions as in the Plan.

The details of the RSUs, in addition to those set forth in the Grant Notice and the Plan, are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. Vesting; No Shareholder Rights.** The RSUs will vest as provided in Participant's Grant Notice. Vesting will cease upon the termination of Participant's service with the Company except as may be provided otherwise in the Vesting Schedule in **<u>Exhibit A</u>** to Participant's Grant Notice. Participant will not be deemed to be the holder of, or have any of the rights of a stockholder with respect to any RSUs unless and until Participant has vested and the Company has issued and delivered Common Shares to Participant and Participant's name shall have been entered as a stockholder of record on the books of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2. Number of RSUs.** The number of RSUs are set forth in Participant's Grant Notice and will be adjusted in the event of changes in capital structure and similar events as provided in Section 12 of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3. Settlement.** Subject to <u>Section 8</u>, as soon as practicable following each Vesting Date (but in no event later than thirty (30) days following such Vesting Date), the Company shall, or its transfer agent shall, in the Board's discretion: (a) transfer one (1) Common Share for each outstanding and vested RSU, (b) transfer cash in an amount equal to the Fair Market Value of the Common Shares underlying the vested RSUs, or (c) transfer a combination of cash and Common Shares. Such transfer shall be contingent upon compliance, to the satisfaction of the Board, with all requirements under applicable laws or regulations in connection with such transfer and with the requirements of this Grant Notice, the Agreement, and of the Plan. The determination of the Board as to such compliance shall be final and binding on Participant. Participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Common Shares subject to this Grant Notice unless and until the Company or the transfer agent shall have transferred the Common Shares to Participant, and Participant's name shall have been entered as the stockholder of record on the books of the Company. Thereupon, Participant shall have full voting, dividend and other ownership rights with respect to such Common Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4. Securities Law Compliance.** In no event shall the Company deliver Common Shares upon vesting of the RSUs unless such shares are then registered under the Securities Act or, if not registered, the Company has determined that the issuance of the shares would be exempt from the registration requirements of the Securities Act. The issuance of Common Shares is also subject to compliance with all other applicable laws and regulations and shall be subject to any applicable lockups and restrictions on resale.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5. Other Terms.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In considering the acceptance of this award of RSUs, Participant understands, acknowledges, agrees and hereby stipulates that Participant should use the same independent investment judgment that Participant would use in making other investments in corporate securities. Among other things, stock prices will fluctuate over any reasonable period of time and the price of Common Shares may go down as well as up. No guarantees are made as to the future prospects of the Company or the Common Shares. No representations are made by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Notwithstanding anything to the contrary in this Agreement, the Common Shares issued under this Agreement, any other restricted stock unit agreement or any stock option agreement, and all amounts that may be received by Participant in connection with any disposition of any such Common Shares shall be subject to applicable recoupment, "clawback" and similar provisions under law, as well as any recoupment, "clawback" and similar policies of the Company that may be adopted at any time and from time to time in order to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, other applicable law or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6. Transferability.** Except as otherwise provided in this <u>Section 6</u> or in the Plan, the RSUs are not assignable or transferable, except by will or by the laws of descent and distribution. Without limiting the generality of the foregoing, the RSUs may not be sold, assigned, transferred or otherwise disposed of, or pledged or hypothecated in any manner (whether by operation of law or otherwise), and shall not be subject to execution, attachment or other process. Any assignment, transfer, sale, pledge, hypothecation or other disposition of the RSUs or any attempt to make any such levy of execution, attachment or other process will cause the RSUs to terminate immediately, unless the Chief Executive Officer of the Company, in his sole discretion, specifically waives applicability of this provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Certain Trusts*. Upon receiving written permission from the Chief Executive Officer of the Company, Participant may transfer the RSUs to a trust if Participant is considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the RSUs are held in the trust. Participant and the trustee must enter into transfer and other agreements required by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Domestic Relations Orders*. Upon receiving written permission from the Chief Executive Officer of the Company, and provided that Participant and the designated transferee enter into transfer and other agreements required by the Company, Participant may transfer the RSUs pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument that contains the information required by the Company to effectuate the transfer. Participant is encouraged to discuss the proposed terms of any division of these RSUs with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Beneficiary Designation*. Upon receiving written permission from the Chief Executive Officer of the Company, Participant may, by delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to administer its equity program, designate a third party who, on Participant's death, will thereafter be entitled to receive the Common Shares or other consideration in settlement of the vested RSUs. In the absence of such a designation, Participant's executor or administrator of Participant's estate will be entitled to receive, on behalf of Participant's estate, the Common Shares or other consideration in settlement of the vested RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7. RSUs not a Service Contract.** The RSUs are not an employment or service contract, and nothing in the RSUs will be deemed to create in any way whatsoever any obligation on Participant's part to continue in the employ or service of the Company or an Affiliate, or of the Company or an Affiliate to continue Participant's employment or service. In addition, nothing in the RSUs will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue any relationship that Participant might have as a member of the Company's Board or a consultant for the Company or an Affiliate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8. Withholding Obligations.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) At the time the RSUs vest, in whole or in part, and at any time thereafter as requested by the Company, Participant hereby agrees to make adequate provision for (including by means of a "same day sale" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the vesting and settlement of the RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that Participant fails to make the adequate provisions contemplated by <u>Section 8(a)</u> above, then, subject to compliance with any applicable legal conditions or restrictions, the Company shall have the option in its sole discretion (but not the obligation) to withhold from fully vested Common Shares otherwise issuable to Participant upon the settlement of the RSUs a number of whole Common Shares having a Fair Market Value, determined by the Company as of the date of vesting or settlement as applicable, not in excess of the amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of the RSUs as a liability for financial accounting purposes).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company assumes no responsibility for individual income taxes, penalties or interest related to grant, vesting or settlement of any RSU. Neither the Company nor any affiliate makes any representation or undertaking regarding the treatment of any tax withholding in connection with the grant, vesting or settlement of the RSUs. Participant should consult with Participant's personal tax advisor regarding the tax ramifications, if any, which result from receipt of the RSUs, the subsequent issuance, if any, of Common Shares on settlement of the RSUs, and subsequent disposition of any such Common Shares. Participant acknowledges that the Company may be required to withhold federal, state and/or local taxes in connection with the vesting and/or settlement of the RSUs. No RSUs will vest or be settled unless and until Participant has made the adequate provisions contemplated by <u>Section 8(a)</u> or the Company has exercised its option to withhold the necessary amount of Common Shares pursuant to <u>Section 8(b)</u> above. The Company will have no obligation to issue a certificate for Common Shares in respect of the RSUs unless the obligations set forth in this <u>Section 8</u> are satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9. Section 409A; Tax Consequences.** It is the Company's intent that payments under this Agreement and Grant Notice shall be exempt from Section 409A of the Internal Revenue Code ("***Section 409A***") to the extent applicable, and that this Agreement be administered accordingly. Notwithstanding anything to the contrary contained in this Agreement, Grant Notice or any employment agreement Participant has entered into with the Company, to the extent that any payment or benefit under this Agreement is determined by the Company to constitute "non-qualified deferred compensation" subject to Section 409A and is payable to Participant by reason of termination of Participant's employment, then (a) such payment or benefit shall be made or provided to Participant only upon a "separation from service" as defined for purposes of Section 409A under applicable regulations and (b) if Participant is a "specified employee" (within the meaning of Section 409A and as determined by the Company), such payment or benefit shall not be made or provided before the date that is six months and one day after the date of Participant's separation from service (or earlier death). Each payment under this Agreement shall be treated as a separate payment under Section 409A. Participant hereby agrees that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes Participant's tax liabilities. Participant will not make any claim against the Company, or any of its officers, directors, employees or Affiliates related to tax liabilities arising from the RSUs or Participant's other compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10. Notices.** Any notices provided for in this Agreement or the Plan will be given in writing and will be deemed effectively given upon receipt. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and these RSUs by electronic means or to request Participant's consent to participate in the Plan by electronic means. By accepting these RSUs, Participant consents to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11. Agreement Summaries.** In the event that the Company provides Participant (or anyone acting on Participant's behalf) with summary or other information concerning, including or otherwise relating to rights or benefits under this Agreement (including, without limitation, the RSUs and any vesting thereof), such summary or other information shall in all cases be qualified in its entirety by **<u>Exhibit A</u>**, the Grant Notice, this Agreement and the Plan and, unless it explicitly states otherwise and is signed by an officer of the Company, shall not constitute an amendment or other modification hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**12. Acknowledgements.** Participant understands, acknowledges, agrees and hereby stipulates that: (a) Participant is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else; (b) the RSUs are intended to be consideration in exchange for the promises and covenants set forth in this Agreement; (c) Participant has carefully read, considered and understand all of the provisions of this Agreement and the Company's policies reflected in this Agreement; (d) Participant has asked any questions needed for Participant to understand the terms, consequences and binding effect of this Agreement and Participant fully understands them; (e) Participant was provided an opportunity to seek the advice of an attorney and/or a tax professional of Participant's choice before accepting this award of RSUs and (f) the obligations and restrictions set forth in this Agreement are fair and reasonable. In addition, Participant understands, acknowledges, agrees and hereby stipulates that (1) Participant explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant's personal data as described in this Agreement and any other award materials by and among the Company and its Affiliates for the purpose of implementing, administering and managing participation in the Plan; (2) Participant understands that the Company may hold certain personal information about Participant, including, but not limited to, Participant's name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all awards, or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in Participant's favor ("***Data***"), for the purpose of implementing, administering and managing the Plan; (3) Participant understands that Data will be transferred to such stock plan service provider as may be selected by the Company, presently or in the future, which may be assisting the Company with the implementation, administration and management of the Plan; (4) Participant authorizes the Company, the stock plan service provider as may be selected by the Company, and any other possible recipients which may assist the Company, presently or in the future, with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing Participant's participation in the Plan; (5) Participant understands that Participant is providing the consents herein on a purely voluntary basis.; (6) if Participant does not consent, or if Participant later seeks to revoke consent, or instruct the Company to cease the processing of the Data, Participant's employment status will not be adversely affected and the only adverse consequence of refusing or withdrawing Participant's consent or instructing the Company to cease processing, is that the Company would not be able to grant Participant RSUs or any other equity awards or administer or maintain such awards; and (7) Participant understands that refusing or withdrawing consent may affect Participant's ability to participate in the Plan.

The details of this Option, in addition to those set forth in the Grant Notice and the Plan, are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. <u>Vesting; No Shareholder Rights</u>.** This Option will vest as provided in your Grant Notice. vesting will cease upon the termination of your employment or service with the Company and its Affiliates, except as may be provided otherwise in the Vesting Schedule in **<u>Exhibit A</u>** to your Grant Notice. You will not be deemed to be the holder of, or have any of the rights of, a stockholder with respect to this Option unless and until this Option vests and you exercise this Option in accordance with this Agreement and the Company has issued and delivered Common Shares to you and your name shall have been entered as a stockholder of record on the books of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2. <u>Number of Shares and Exercise Price</u>.** The number of Common Shares subject to this Option and your Exercise Price per share are set forth in your Grant Notice and will be adjusted in the event of changes in capital structure and similar events as provided in Section 12 of the Plan.

This manner of payment is also known as a "cashless exercise", "broker-assisted exercise", "same day sale", or "sell to cover".

You must pay any remaining balance of the aggregate exercise price not satisfied by the "net exercise" in cash or other permitted form of payment. Common Shares will no longer be outstanding under this Option and will not be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the "net exercise," (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5. <u>Whole Shares</u>.** You may exercise this Option only for whole Common Shares unless pursuant to the terms of your Grant Notice you were granted an option to purchase fractional Common Shares or your vesting schedule provides for vesting in fractional shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6. <u>Securities and Other Law Compliance</u>.** In no event may you exercise this Option unless the Common Shares issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the registration requirements of the Securities Act. The exercise of this Option also must comply with all other Applicable Laws and regulations governing this Option (including pursuant to an International Addendum, if applicable), and you may not exercise this Option if the Company determines that such exercise would not be in material compliance with such laws and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7. <u>Term</u>.** You may not exercise this Option before the Date of Grant or after the expiration of this Option's term. Except as may be provided otherwise in the Vesting Schedule in **<u>Exhibit A</u>** to your Grant Notice or in an employment or other agreement between you and the Company, the term of this Option expires (subject to the provisions of Section 7(c) of the Plan in the event that this Option is an Incentive Stock Option and you, on the Date of Grant, own shares representing more than ten percent (10%) of the combined voting power of the Company) upon the earliest of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) immediately upon the termination of your service with the Company or an Affiliate for Cause;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) ninety (90) days after the termination of your service with the Company or an Affiliate for any reason other than Cause, your Disability (as defined below) or your death (except as otherwise provided in <u>Section 7(d)</u> below); provided, however, that if during any part of such ninety (90) day period this Option is not exercisable solely because of the condition set forth in the section above relating to "Securities Law Compliance," this Option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of ninety (90) days after the termination of your service with the Company or an Affiliate; provided further, that if (i) you are a Non-Exempt Employee, (ii) your service with the Company or an Affiliate terminates within six (6) months after the Date of Grant, and (iii) you have vested in a portion of this Option at the time of your termination of your service with the Company or an Affiliate, this Option will not expire until the earlier of (x) the later of (A) the date that is one hundred and twenty (120) days after the Date of Grant, and (B) the date that is ninety (90) days after the termination of your service with the Company or an Affiliate, and (y) the Expiration Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) one (1) year after the termination of your service with the Company or an Affiliate due to your Disability (except as otherwise provided in <u>Section 7(d)</u>) below. For purposes of this Agreement, "***Disability***" means your inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than twelve (12) months as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined by the Committee on the basis of such medical evidence as the Committee deems warranted under the circumstances;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) one (1) year after your death if you die either during your service with the Company or within ninety (90) days after your service with the Company terminates for any reason other than Cause;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the Expiration Date indicated in your Grant Notice; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the day before the tenth (10<sup>th</sup>) anniversary of the Date of Grant.

If this Option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option, the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of this Option's exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of this Option under certain circumstances for your benefit but cannot guarantee that this Option will necessarily be treated as an Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a consultant or director after your employment terminates or if you otherwise exercise this Option more than three (3) months after the date your employment with the Company or an Affiliate terminates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8. <u>Exercise</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) You may exercise the vested portion of this Option during its term by (i) delivering a Notice of Exercise (in a form designated by the Company) and completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the Exercise Price and any applicable withholding taxes to the Company's Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) By exercising this Option you agree that, as a condition to any exercise of this Option, the Company may require you and you hereby agree to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of this Option, or (ii) the disposition of Common Shares acquired upon such exercise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If this Option is an Incentive Stock Option, by exercising this Option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Shares issued upon exercise of this Option that occurs within two (2) years after the Date of Grant or within one (1) year after such Common Shares are transferred upon exercise of this Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9. <u>Transferability</u>.** Except as otherwise provided in this <u>Section 9</u>, this Option is not assignable or transferable, except by will or by the laws of descent and distribution and is exercisable during your life only by you. Without limiting the generality of the foregoing, this Option may not be sold, assigned, transferred or otherwise disposed of, or pledged or hypothecated in any manner (whether by operation of law or otherwise), and shall not be subject to execution, attachment or other process. Any assignment, transfer, sale, pledge, hypothecation or other disposition of this Option or any attempt to make any such levy of execution, attachment or other process will cause this Option to terminate immediately, unless the Chief Executive Officer of the Company, in his sole discretion, specifically waives applicability of this provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Certain Trusts*. Upon receiving written permission from the Chief Executive Officer of the Company, you may transfer this Option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while this Option is held in the trust. You and the trustee must enter into transfer and other agreements required by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Domestic Relations Orders*. Upon receiving written permission from the Chief Executive Officer of the Company, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer this Option pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this Option with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement agreement. If this Option is an Incentive Stock Option, this Option may be deemed to be a Non-Qualified Stock Option as a result of such transfer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Beneficiary Designation*. Upon receiving written permission from the Chief Executive Officer of the Company, you may, by delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to exercise this Option and receive the Common Shares or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate will be entitled to exercise this Option and receive, on behalf of your estate, the Common Shares or other consideration resulting from such exercise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10. <u>Option not a Service Contract</u>.** This Option is not an employment or service contract, and nothing in this Option will be deemed to create in any way whatsoever any obligation on your part to continue in the employ or service of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment or service. In addition, nothing in this Option will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue any relationship that you might have as a member of the Company's Board or a consultant for the Company or an Affiliate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11. <u>Withholding Obligations</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) At the time you exercise this Option, in whole or in part, and at any time thereafter as requested by the Company, you hereby agree to make adequate provision for (including by means of a "same day sale" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of this Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that you fail to make the adequate provisions contemplated by <u>Section 11(a)</u> above, then subject to compliance with any applicable legal conditions or restrictions, the Company shall have the option in its discretion (but not the obligation) to withhold from fully vested Common Shares otherwise issuable to you upon the exercise of this Option a number of whole Common Shares having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of this Option as a liability for financial accounting purposes).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company assumes no responsibility for individual income taxes, penalties or interest related to grant or exercise of any option. Neither the Company nor any affiliate makes any representation or undertaking regarding the treatment of any tax withholding in connection with the grant or exercise of any option. You should consult with your personal tax advisor regarding the tax ramifications, if any, which result from receipt of this Option, the subsequent issuance, if any, of Common Shares on exercise of this Option, and subsequent disposition of any such Common Shares. You acknowledge that the Company may be required to withhold federal, state and/or local taxes in connection with the exercise of this Option. You may not exercise this Option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise this Option when desired even though this Option is vested, and the Company will have no obligation to issue a certificate for such Common Shares or release such Common Shares from any escrow provided for herein, if applicable, unless such obligations are satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**12. <u>Section 409A; Tax Consequences</u>.** It is the Company's intent that this Option be exempt from Section 409A of the Internal Revenue Code to the extent applicable, and that this Agreement be administered accordingly. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim against the Company, or any of its officers, directors, employees or Affiliates related to tax liabilities arising from this Option or your other compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**13. <u>Notices</u>.** Any notices provided for in this Option or the Plan will be given in writing and will be deemed effectively given upon receipt. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Option by electronic means or to request your consent to participate in the Plan by electronic means. By accepting this Option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**14. <u>Agreement Summaries</u>.** In the event that the Company provides you (or anyone acting on your behalf) with summary or other information concerning, including or otherwise relating to your rights or benefits under this Agreement (including, without limitation, this Option and any exercise thereof), such summary or other information shall in all cases be qualified in its entirety by **<u>Exhibit A</u>**, **<u>Exhibit B</u>**, the Grant Notice, this Agreement, the Plan and the Notice of Exercise and, unless it explicitly states otherwise and is signed by an officer of the Company, shall not constitute an amendment or other modification hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**15. <u>Clawback</u>.** Notwithstanding anything to the contrary in this Agreement, the Common Shares issued in connection with this Agreement, any restricted stock unit agreement or any other stock option agreement, and all amounts that may be received by you in connection with any disposition of any such Common Shares shall be subject to applicable recoupment, "clawback" and similar provisions under Applicable Law, as well as any recoupment, "clawback" and similar policies of the Company that may be adopted at any time and from time to time for any reason, including in order to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**16. <u>Acknowledgements</u>.** You understand, acknowledge, agree and hereby stipulate that: (a) you are executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else; (b) this Option is intended to be consideration in exchange for the promises and covenants set forth in this Agreement; (c) you have carefully read, considered and understand all of the provisions of this Agreement and the Company's policies reflected in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged; (d) you have asked any questions needed for you to understand the terms, consequences and binding effect of this Agreement and you fully understand them; (e) you were provided an opportunity to seek the advice of an attorney and/or a tax professional of your choice before accepting this Option and (f) the obligations and restrictions set forth in this Agreement are fair and reasonable. In addition, you understand, acknowledge, agree and hereby stipulate that (1) you explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of your personal data as described in this Agreement and any other award materials by and among the Company and its Affiliates for the purpose of implementing, administering and managing your participation in the Plan; (2) you understand that the Company may hold certain personal information about you, including, but not limited to, the your name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all awards, or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in your favor ("***Data***"), for the purpose of implementing, administering and managing the Plan; (3) you understand that Data will be transferred to such stock plan service provider as may be selected by the Company, presently or in the future, which may be assisting the Company with the implementation, administration and management of the Plan; (4) you authorize the Company, the stock plan service provider as may be selected by the Company, and any other possible recipients which may assist the Company, presently or in the future, with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing your participation in the Plan; (5) you understand that you are providing the consents herein on a purely voluntary basis.; (6) if you do not consent, or if you later seeks to revoke your consent, or instruct the Company to cease the processing of the Data, your employment status will not be adversely affected and the only adverse consequence of refusing or withdrawing your consent or instructing the Company to cease processing, is that the Company would not be able to grant you options or any other equity awards or administer or maintain such awards; and (7) you understand that refusing or withdrawing your consent may affect your ability to participate in the Plan.

Ladies and Gentlemen:

We have acted as counsel to Abpro Holdings, Inc., a Delaware corporation (the "**Company**"), in connection with the Registration Statement on Form S-8 (the "**Registration Statement**") to be filed by the Company on or about June 18, 2025 with the U.S. Securities and Exchange Commission (the "**SEC**") under the Securities Act of 1933, as amended, related to the offering of up to an aggregate of 6,240,773 shares (the "**Company Shares**") of the Company's common stock, par value $0.0001 per share (the "**Common Stock**"), issuable under the Abpro Holdings, Inc. 2024 Equity Incentive Plan (the "**2024 Plan**"). In addition, the Registration Statement registers the resale of up to 6,985,959 shares (the "**Rollover Shares**" and, together with the Company Shares, the "**Shares**") of Common Stock issuable to certain selling stockholders listed in in the reoffer prospectus included in the Registration Statement (the "**Reoffer Prospectus**") upon the exercise or settlement of Rollover Options and Rollover RSUs (each as defined in the Reoffer Prospectus), respectively, that were originally issued by Abpro Corporation ("**Abpro**") pursuant to the Abpro Corporation 2014 Stock Incentive Plan (the "**Abpro Plan**"), such Rollover Shares being assumed under the 2024 Plan. This opinion letter is furnished pursuant to the requirement of Item 601(b)(5) of Regulation S-K promulgated by the SEC.

In reaching the opinions set forth herein, we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such documents and records of the Company and such statutes, regulations and other instruments, certificates and records as we deem necessary or advisable for the purposes of this opinion letter, including, without limitation, the 2024 Plan, the Abpro Plan, the Company's Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and certain resolutions adopted by the Company's board of directors.

As to any facts material to our opinions, we have made no independent investigation or verification of such facts and have relied, to the extent that we deem such reliance proper, on certificates and oral or written statements and other information of or from officers and representatives of the Company and public officials and on factual information included in the Company's filings with the SEC. We have assumed the completeness and authenticity of all documents submitted to us as originals, the completeness and conformity to the originals of all documents submitted to us as copies thereof, the genuineness of all signatures, the legal capacity and mental competence of natural persons, and that all information contained in all documents reviewed by us is true, correct and complete. In addition, we have assumed that the Shares will be issued in accordance with the 2024 Plan, as applicable, and that the Company will receive legal consideration for the issuance of the Shares (in an amount not less than the par value thereof).

On the basis of the foregoing, and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth below, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Company Shares that may be issued and sold from time to time in accordance with the 2024 Plan have
been duly authorized and, when issued and delivered in accordance with the 2024 Plan, the Company Shares will be validly issued, fully
paid and nonassessable.

Abpro Holdings, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Rollover Shares will upon the due and valid exercise or settlement of the Rollover Options and Rollover
RSUs, respectively, in accordance with the Abpro Plan and the terms of binding agreements in respect of such Rollover Options and Rollover
RSUs entered into between Abpro and the persons being granted such Rollover Options and Rollover RSUs, and in the case of a Rollover Option,
receipt by the Company of payment in full for each such Rollover Share to be issued upon the exercise of such Rollover Option, be validly
issued and outstanding as fully paid and non-assessable Common Stock of the Company.

This opinion letter is rendered as of the date hereof, and we assume no obligations to advise you of changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may come to our attention. We hereby consent to the filing of this opinion letter with the SEC as Exhibit 5.1 to the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the SEC.

Our opinions are based upon and limited to the Delaware General Corporation Law, and no opinion is expressed as to the laws of any other jurisdiction. We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or "Blue Sky" laws of the various states to the issuance and sale of any of the Shares.
