PROPOSAL NO. 1

APPROVAL, IN ACCORDANCE WITH NASDAQ MARKETPLACE RULE 5635(D), OF THE ISSUANCE OF OUR COMMON STOCK TO YORKVILLE IN EXCESS OF THE EXCHANGE CAP OF THE STANDBY EQUITY PURCHASE AGREEMENT DATED APRIL 28, 2022, BY AND BETWEEN THE COMPANY AND YORKVILLE (THE “EXCHANGE CAP PROPOSAL”)

Background

As previously disclosed, on April 28, 2022, we entered into a Standby Equity Purchase Agreement (the “SEPA,” included as Appendix A to this Proxy Statement) with YA II PN, Ltd. (“Yorkville”). Pursuant to the SEPA, the Company has the right, but not the obligation, to sell to Yorkville up to $200,000,000 of its shares of common stock (the “SEPA Shares”), par value $0.0001 per share, at the Company’s request any time during the commitment period commencing on April 28, 2022 and terminating on the earliest of (i) the first day of the month following the 24-month anniversary of the SEPA and (ii) the date on which Yorkville has made payment of any advances requested pursuant to the SEPA for shares of the Company’s common stock equal to the commitment amount of $200,000,000. Each sale the Company requests under the SEPA (an “Advance”) may be for a number of shares of common stock with an aggregate value of up to $20,000,000. The shares would be purchased at 97.0% of the Market Price (as defined below) and would be subject to certain limitations, including that Yorkville could not purchase any shares that would result in it owning more than 9.99% of the Company’s outstanding common stock at the time of an Advance (the "Ownership Limitation") or 19.99% of the Company's outstanding common stock as of the date of the SEPA (the "Exchange Cap"). “Market Price” is defined in the SEPA as the average of the VWAPs (as defined below) during each of the three consecutive trading days commencing on the trading day following the Company’s submission of an Advance notice to Yorkville. “VWAP” is defined in the SEPA to mean, for any trading day, the daily volume weighted average price of the Company’s common stock for such date on The Nasdaq Capital Market as reported by Bloomberg L.P. during regular trading hours.

As of the date of the SEPA, there were 53,980,608 shares of the Company’s common stock issued and outstanding. Accordingly, the Exchange Cap is 10,790,723 shares. The SEPA provides that (a) the Exchange Cap will not apply if the Company’s stockholders have approved issuances in excess of the Exchange Cap in accordance with the rules of The Nasdaq Capital Market, and (b) as to any Advance, if the purchase price of shares in respect of such Advance equals or exceeds $2.15 per share (which represents the lower of (i) the closing price of common stock as reported on the “Historical NOCP” section of the web site Nasdaq.com for the ticker symbol “EOSE.” (the “Nasdaq Official Closing Price”) on the trading day immediately preceding the date of the SEPA; or (ii) the average Nasdaq Official Closing Price for the five trading days immediately preceding the date of the SEPA). As of the date of this proxy statement, we have offered and sold to Yorkville an aggregate of 3,967,939 shares of our common stock, all of which are counted against the Exchange Cap.

Pursuant to the SEPA, we will use the proceeds from the sale of SEPA Shares for working capital and other general corporate purposes or, if different, in a manner consistent with the application thereof described in the registration statement pursuant to which such shares are registered with the SEC. There are no other restrictions in the SEPA on future financing transactions, provided such use of proceeds also does not violate the laws and regulations set forth by the U.S. Office of Foreign Assets Control.

Reasons for Seeking Stockholder Approval

Our common stock is currently listed on The Nasdaq Capital Market and, as such, we are subject to Nasdaq Marketplace Rules (the “Nasdaq Rules”). Nasdaq Listing Rule 5635(d) requires us to obtain stockholder approval

3

prior to the sale, issuance or potential issuance of common stock (or securities convertible into or exercisable for common stock) in connection with a transaction other than a public offering at a price less than the “Minimum Price” which either alone or together with sales by officers, directors or substantial stockholders of the company equals 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance. For Nasdaq purposes, “Minimum Price” means a price that is the lower of: (i) the Nasdaq Official Closing Price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq Official Closing Price of the common stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement. Stockholder approval of this proposal will constitute stockholder approval for purposes of Nasdaq Listing Rule 5635(d). Our Board has determined that the SEPA and our ability to issue the SEPA Shares thereunder in excess of the Exchange Cap is in the best interests of the Company and its stockholders because the ability to sell the SEPA Shares to Yorkville provides us with a reliable source of capital for working capital and general corporate purposes.

We cannot predict the Market Price (as defined above) of our common stock at any future date, and therefore cannot predict the number of SEPA Shares to be issued under the SEPA or whether the Market Price for any Advance will be greater than the Minimum Price (as defined above) under the Nasdaq Rules. Under certain circumstances, it is possible that we may need to issue shares of common stock to Yorkville at a price that is less than the Minimum Price in excess of the Exchange Cap, which would require stockholder approval pursuant to Nasdaq Listing Rule 5635(d).

Therefore, we are seeking stockholder approval under this Proposal No. 1 to issue shares of common stock in excess of the Exchange Cap, if necessary, to Yorkville under the terms of the SEPA. The failure of the Company’s stockholders to approve this Proposal No. 1 will make it impossible for the Company to sell, at less than the Minimum Price, shares of common stock to Yorkville in excess of the Exchange Cap. However, it would be possible to sell shares to Yorkville in excess of the Exchange Cap if the sale of shares covered by any Advance is equal to or greater than the Minimum Price for such Advance.

Consequences of Non-Approval

As previously disclosed, as of December 31, 2021, the Company concluded that there was substantial doubt about its ability to continue to operate as a going concern for the 12 months following the issuance of its consolidated financial statements. The ability of the Company to continue as a going concern is dependent upon the Company’s ability to access additional sources of capital, including, but not limited to, equity and/or debt financings, licensing revenue, and government loans or grants. If the Company is unable to raise additional capital, the Company may have to significantly delay, scale back or discontinue the development or commercialization of its product and/or consider a sale or other strategic transaction. Accordingly, our Board believes that providing the Company the flexibility to issue shares of common stock in excess of the Exchange Cap is advisable and in the best interests of the Company and our stockholders.

Effect on Current Stockholders

The issuance of shares of common stock under the SEPA, including any shares that may be issued in excess of the Exchange Cap (including any such shares issued below the Minimum Price that are the subject of this Proposal No. 1), would result in an increase in the number of shares of common stock outstanding, and our stockholders will incur dilution of their percentage ownership. Because the number of SEPA Shares that may be issued to Yorkville pursuant to the SEPA is determined based on the Market Price at the time of issuance, the exact magnitude of the dilutive effect cannot be conclusively determined. However, the dilutive effect may be material to our current stockholders.

Required Vote

Approval of Proposal No. 1 requires the affirmative vote of a majority of the votes cast on the proposal. Abstentions and “broker non-votes,” if any, will have no effect on the outcome of this vote.

THE BOARD RECOMMENDS A VOTE

FOR APPROVAL, IN ACCORDANCE WITH NASDAQ MARKETPLACE RULE 5635(D), OF THE ISSUANCE OF OUR COMMON STOCK TO YORKVILLE IN EXCESS OF THE EXCHANGE CAP OF THE STANDBY EQUITY PURCHASE AGREEMENT DATED APRIL 28, 2022, BY AND BETWEEN THE COMPANY AND YORKVILLE

PROPOSAL NO. 2

APPROVAL OF AN AMENDMENT TO OUR THIRD AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE AUTHORIZED SHARES OF COMMON STOCK FROM 200,000,000 TO 300,000,000 (THE “AUTHORIZED SHARES AMENDMENT”)

After careful consideration, the Board has adopted, declared advisable and directed that there be submitted to the stockholders at the Special Meeting a proposed amendment of the Company’s Third Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) to increase the number of shares of authorized common stock from 200,000,000 to 300,000,000.

Background

Article IV of the Certificate of Incorporation currently authorizes the Company to issue up to 200,000,000 shares of common stock and 1,000,000 shares of preferred stock of the Company, par value $0.0001 per share (“preferred stock”). As of May 25, 2022, approximately 58,503,554 shares of common stock were issued, including zero held as treasury shares, with warrants outstanding to purchase up to an aggregate of 7,326,654 shares of common stock, options and restricted stock units outstanding to acquire up to an aggregate of 5,099,774 shares of common stock, approximately 3,536,607 shares of common stock reserved for possible future issuance pursuant to the remaining authorized and unissued stock awards under the Amended and Restated 2020 Incentive Plan and a maximum of 6,516,359 shares of common stock issuable upon conversion of the Company’s outstanding 5%/6% Convertible Senior PIK Toggle Notes due 2026. As a result, approximately 119,017,052 authorized shares remain available for issuance for future purposes. The adoption of the proposed Authorized Shares Amendment would provide for an additional 100,000,000 authorized shares of common stock for future issuance, which would bring the aggregate total of authorized shares of common stock to 300,000,000.

The Authorized Shares Amendment amends and restates Section 4.1(b) of Article IV of the Certificate of Incorporation in its entirety to read as follows:

The total number of shares of all classes of capital stock, each with a par value of $0.0001 per share, which the Corporation is authorized to issue is 301,000,000 shares, consisting of (a) 300,000,000 shares of common stock (the “Common Stock”) and (b) 1,000,000 shares of preferred stock (the “Preferred Stock”).

Reasons for Seeking Stockholder Approval

As of May 25, 2022, the Company had approximately 60% of the authorized shares of common stock unissued and unreserved for issuance. The additional shares may be used for various purposes without further stockholder approval (except as required by law or Nasdaq rules). These purposes may include: (i) raising capital, if the Company has an appropriate opportunity, through offerings of common stock or securities that are convertible into common stock, including sales of common stock pursuant to the SEPA described above in Proposal No. 1; (ii) exchanging common stock or securities that are convertible into common stock for other outstanding securities; (iii) providing equity incentives to employees, officers, directors, customers, consultants, or advisors; (iv) expanding the Company’s business through the acquisition of other businesses or assets; (v) stock splits, dividends, and similar transactions; (vi) debt or equity restructuring or refinancing transactions; and (vii) other corporate purposes.

6

The Board has not proposed the increase in the number of authorized shares of common stock with the intent of preventing or discouraging any actual or threatened tender offers or takeover attempts of the Company and the Board is not currently aware of any attempt or plan to acquire control of the Company. Rather, the Authorized Shares Amendment has been prompted by business and financial considerations, as set out above, and it is the intended purpose of the Authorized Shares Amendment to provide greater flexibility to the Board in considering and planning for our potential future corporate needs.

Rights of Additional Authorized Shares

The additional authorized shares contemplated by the Authorized Shares Amendment would be a part of the existing class of our common stock and, if issued, would have the same rights and privileges as the shares of our common stock presently issued and outstanding. Holders of shares of our common stock (solely in their capacity as holders of shares of our common stock) have no preemptive rights or rights to convert their shares of our common stock into any other securities. Accordingly, should the Board elect to issue additional shares of our common stock, existing holders of shares of our common stock would not have any preferential rights to purchase the shares.

Effect on Current Stockholders

Future issuance of common stock or securities convertible into our common stock could have a dilutive effect on the earnings per share, book value per share, voting power and percentage interest of holdings of current stockholders. In addition, the availability of additional shares of our common stock for issuance could, under certain circumstances, discourage or make more difficult efforts to obtain control of the Company under a possible take-over scenario. The Board is not aware of any attempt, or contemplated attempt, to acquire control of the Company. This proposal is not being presented with the intent that it be used to prevent or discourage any acquisition attempt, but nothing would prevent the Board from taking any appropriate actions not inconsistent with its fiduciary duties. The Authorized Shares Amendment does not affect the number of shares or rights of preferred stock authorized.

Effectiveness of the Amendment

If this proposal is approved by the Company’s stockholders, the Authorized Shares Amendment will become effective upon the filing of a Certificate of Amendment to the Certificate of Incorporation with the Delaware Secretary of State, which the Company intends to do promptly following the Annual Meeting. If the proposal is not approved by the Company’s stockholders, the Authorized Shares Amendment will not be implemented and the Company’s capitalization will remain as it is currently.

Required Vote

Approval of Proposal No. 2 requires the affirmative vote of the holders of at least 662⁄3% of outstanding shares of our common stock as of the Record Date to approve the amendment to the Certificate of Incorporation to increase the authorized shares of common stock. Abstentions and “broker non-votes”, if any, will have the effect of votes “AGAINST” the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

FOR APPROVAL OF AN AMENDMENT TO OUR THIRD AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE AUTHORIZED SHARES OF COMMON STOCK FROM 200,000,000 TO 300,000,000.

7

PROPOSAL NO. 3

APPROVAL OF AN ADJOURNMENT OF THE SPECIAL MEETING, IF NECESSARY, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF THE EXCHANGE CAP PROPOSAL AND/OR THE AUTHORIZED SHARES AMENDMENT

At the Special Meeting, if necessary, stockholders will vote on this Proposal No. 3. If this Proposal No. 3 is adopted, the Board will have the discretion to adjourn the Special Meeting to a later date or dates to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the Special Meeting to approve Proposal No. 1 and/or Proposal No. 2. It is possible for us to obtain sufficient votes to approve this Proposal No. 3 but not receive sufficient votes to approve Proposal No. 1 and/or Proposal No. 2. In such a situation, the Company could adjourn the Special Meeting for any number of days or hours as permitted under applicable law and attempt to solicit additional votes in favor of Proposal No. 1 and/or Proposal No. 2.

This Proposal No. 3 will only be presented at the Special Meeting if there are not sufficient votes represented in person or by proxy for Proposal No. 1 and/or Proposal No. 2.

Required Vote

The approval of Proposal No. 3 requires the affirmative vote of a majority of the votes cast on the proposal. Abstentions and “broker non-votes,” if any, will have no effect on the outcome of this vote.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE

FOR APPROVAL OF AN ADJOURNMENT OF THE SPECIAL MEETING, IF NECESSARY, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF THE EXCHANGE CAP PROPOSAL AND/OR THE AUTHORIZED SHARES AMENDMENT.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information relating to the beneficial ownership of our common stock as of May 4, 2022, by:

•each person, or group of affiliated persons, known by us to beneficially own more than 5% of outstanding shares of our common stock;

•each of our directors, nominees and named executive officers; and

•all directors and executive officers as a group.

A person is a “beneficial owner” of a security if that person has or shares voting or investment power over the security or if that person has the right to acquire sole or shared voting or investment power over the security within 60 days. Unless otherwise noted, these persons, to our knowledge, have sole voting and investment power over the shares listed. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of common stock subject to options, warrants and restricted stock units held by that person that are currently exercisable or exercisable within 60 days of May 4, 2022

The percentage of shares beneficially owned is computed on the basis of 54,445,725shares of our common stock outstanding and 7,326,654 warrants, each exercisable for one common stock share, outstanding as of May 4, 2022. Unless otherwise indicated below, the address for each beneficial owner listed is c/o 3920 Park Avenue, Edison, New Jersey 08820.

ADDITIONAL INFORMATION

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

Brokers with account holders who are Eos stockholders may be “householding” our proxy materials. A single proxy statement may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in “householding.”

INFORMATION ABOUT THE PROXY PROCESS AND VOTING

Why am I receiving these materials?

The Board is providing printed proxy materials to you, in connection with the Board’s solicitation of proxies for use at the Company’s Special Meeting to be held on June 28, 2022, at 10:00 a.m. Eastern Time, and at any adjournment or postponement thereof, for the purpose of considering and acting upon the matters set forth in this proxy statement. These proxy materials are being distributed to you beginning on May 27, 2022. As a stockholder, you are invited to attend the virtual Special Meeting and are requested to vote on the proposals described in this proxy statement.

Who can vote at the Special Meeting?

The outstanding voting securities of Eos are shares of common stock, $0.0001 par value per share. There were 58,503,554 shares of common stock outstanding as of May 25, 2022. Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Special Meeting.

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record as of May 25, 2022, you may vote online during the virtual Special Meeting. Alternatively, you may vote by proxy by using the accompanying Proxy Card, over the internet or by telephone. Whether or not you plan to attend online the virtual Special Meeting, we encourage you to vote by proxy ahead of the Special Meeting to ensure your vote is counted. Even if you have submitted a proxy before the Special Meeting, you may still attend the Special Meeting and vote. In such case, your previously submitted proxy will be disregarded.

•To vote using the Proxy Card, simply complete, sign and date the accompanying Proxy Card and return it promptly in the envelope provided. If you return your signed Proxy Card to us before the Special Meeting, we will vote your shares in accordance with the Proxy Card.

•To vote by proxy over the internet before the Special Meeting, follow the instructions as directed on the enclosed Proxy Card.

•To vote by telephone, you may vote by proxy by calling the toll-free number found on the enclosed Proxy Card.

•To vote at the virtual Special Meeting, you will need the 16-digit control number included on your Proxy Card. The meeting webcast will begin promptly at 10:00 a.m., Eastern time. We encourage you to access the meeting prior to the start time. Online log-in will begin at 9:45 a.m. Eastern time, and you should allow ample time for the log-in process. If you encounter any difficulties accessing the virtual meeting during the log-in or meeting time, please call the technical support number that will be posted on the virtual Special Meeting login page for assistance.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

12

If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account.

If you are a beneficial owner as described above, you should have received a voting instruction form from the brokerage firm, bank, dealer or other similar organization that holds your shares. Follow the instructions they provide to ensure that your vote is counted.

We provide internet proxy voting to allow you to vote your shares online before the Special Meeting, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

What is the required vote to approve the proposals discussed in this Proxy Statement?

Approval of the Exchange Cap Proposal and the Adjournment Proposal will require the affirmative vote of the majority of the total votes cast on such proposal. Approval of the Authorized Shares Amendment will require the affirmative vote of the holders of at least 662⁄3% of outstanding shares of our common stock. Abstentions and “broker non-votes,” if any, will have no effect on the outcome of the Exchange Cap Proposal or the Adjournment Proposal. Abstentions and “broker non-votes” will have the effect of votes “AGAINST” the Authorized Shares Amendment.

What are “broker non-votes”?

If your shares are held by your broker as your nominee (that is, in “street name”), you will need to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to “routine” items, but not with respect to “non-routine” items.

If a broker, bank, custodian, nominee or other record holder of common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as “broker non-votes” with respect to that proposal.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the Record Date.

What if I return a Proxy Card but do not make specific choices?

If we receive a signed and dated Proxy Card and the Proxy Card does not specify how your shares are to be voted, your proxy (one of the individuals named on your Proxy Card) will vote your shares in his or her discretion.

What does it mean if I receive more than one set of materials?

If you receive more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must either sign and return all of the Proxy Cards or follow the instructions for any alternative voting procedure on each of the Proxy Cards.

13

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Special Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

•You may submit another properly completed proxy with a later date.

•You may send a written notice that you are revoking your proxy to our Investor Relations Department at 3920 Park Avenue, Edison, New Jersey 08820, 765-201-0591 or email ir@eose.com.

•You may attend the virtual Special Meeting through online presence and vote online. Simply attending the Special Meeting will not, by itself, revoke your prior proxy.

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them.

When are stockholder proposals due for next year’s Annual Meeting?

If you wish to submit a stockholder proposal pursuant to Rule 14a-8 of the Securities Exchange Act to be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 1, 2022 to Eos Energy Enterprises Inc., c/o Laura Ellis, 3920 Park Avenue, Edison, New Jersey 08820, or email at ir@eose.com.

Pursuant to our bylaws, in order for a stockholder to present a proposal at the annual meeting, other than 14a-8 proposals to be included in the Proxy Statement as described above, or to nominate a director, you must give timely notice thereof in writing to the Secretary at Eos Energy Enterprises Inc., 3920 Park Avenue, Edison, New Jersey 08820, which must be received between January 17, 2023 and February 16, 2023; provided that if the date of the 2023 annual meeting is more than 30 days before or after May 17, 2023, notice must be received no earlier than 120 days prior to such annual meeting and no later than the 90th day prior to the annual meeting date or the 10th day following the day on which public announcement of the 2023 annual meeting date is first made by the Company. You are also advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. The presence, in person or represented by proxy, at the Special Meeting of the holders of shares of outstanding common stock representing a majority of the voting power of all outstanding shares of common stock entitled to vote at the Special Meeting will be required to establish a quorum at the Special Meeting. Abstentions and “broker non-votes” will be treated as shares present and entitled to vote for quorum purposes. Your shares will be counted towards the quorum only if you submit a valid proxy or vote at the Special Meeting. If there is no quorum, either the chair of the Special Meeting or a majority in voting power of the stockholders entitled to vote at the Special Meeting, present online or represented by proxy, may adjourn the Special Meeting to another time or place.

How can I find out the results of the voting at the Special Meeting?

Voting results will be announced by the filing of a Current Report on Form 8-K within four business days after the Special Meeting.

Who can help answer my questions?

If you have questions about this Proxy Statement or if you need additional copies of the proxy materials, you should contact our Investor Relations department at 765-201-0591 or ir@eose.com.

Who will solicit and pay the cost of soliciting proxies?

Eos will pay the cost of soliciting proxies for the special meeting. Eos will reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of ordinary shares for their expenses in forwarding soliciting materials to beneficial owners of ordinary shares and in obtaining voting instructions from those owners. Our directors, officers and employees may also solicit proxies by telephone, mail, on the Internet or at the Special Meeting. They will not be paid any additional amounts for soliciting proxies. In addition, we have retained Morrow Sodali to act as a proxy solicitor in conjunction with the Special Meeting. We have agreed to pay that firm $12,500 and reasonable out-of-pocket expenses, for proxy solicitation services.

How do I attend the Special Meeting?

The Board of Directors has determined to hold the Special Meeting virtually to facilitate stockholder attendance and participation by stockholders from all locations at no cost. We believe this is the right choice for the Company at this time, as it enables engagement with our stockholders, regardless of size, resources, or physical location while safeguarding the health of our stockholders, Board and management. We are committed to ensuring that stockholders will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

(a)Advance Notice. At any time during the Commitment Period the Company may require the Investor to purchase Shares by delivering an Advance Notice to the Investor, subject to the conditions set forth in Section 7.01, and in accordance with the following provisions:

(i)The Company shall, in its sole discretion, select the amount of the Advance, not to exceed the Maximum Advance Amount, it desires to issue and sell to the Investor in each Advance Notice and the time it desires to deliver each Advance Notice.

(ii)There shall be no mandatory minimum Advances and no non-usages fee for not utilizing the Commitment Amount or any part thereof.

(b)Date of Delivery of Advance Notice. Advance Notices shall be delivered in accordance with the instructions set forth on the bottom of Exhibit A. An Advance Notice shall be deemed delivered on (i) the day it is received by the Investor if such notice is received by email on or before 8:30 a.m. Eastern Time in

A-4

accordance with the instructions set forth on the bottom of Exhibit A, or (ii) the immediately succeeding day if it is received by email after 8:30 a.m. Eastern Time, in each case in accordance with the instructions set forth on the bottom of Exhibit A.

(c)Advance Limitations. Regardless of the amount of an Advance requested by the Company in the Advance Notice, the final number of Shares to be issued and sold pursuant to an Advance Notice shall be reduced in accordance with each of the following limitations:

(i)Ownership Limitation; Commitment Amount. At the request of the Company, the Investor will inform the Company of the amount of shares the Investor currently beneficially owns. In no event shall the number of Common Shares issuable to the Investor pursuant to an Advance cause the aggregate number of Common Shares beneficially owned (as calculated pursuant to Section 13(d) of the Exchange Act) by the Investor and its Affiliates as a result of previous issuances and sales of Common Shares to Investor under this Agreement to exceed 9.99% of the then outstanding Common Shares (the “Ownership Limitation”). In connection with each Advance Notice delivered by the Company, any portion of the Advance that would (i) cause the Investor to exceed the Ownership Limitation or (ii) cause the aggregate number of Shares issued and sold to the Investor hereunder to exceed the Commitment Amount shall automatically be withdrawn with no further action required by the Company, and such Advance Notice shall be deemed automatically modified to reduce the amount of the Advance requested by an amount equal to such withdrawn portion; provided that in the event of any such automatic withdrawal and automatic modification, the Investor will promptly notify the Company of such event.

(ii)Registration and Exchange Limitation. In no event shall an Advance exceed the amount registered under the Registration Statement then in effect (the “Registration Limitation”) or the Exchange Cap, to the extent applicable. In connection with each Advance Notice, any portion of an Advance that would exceed the Registration Limitation or the Exchange Cap shall automatically be withdrawn with no further action required by the Company and such Advance Notice shall be deemed automatically modified to reduce the aggregate amount of the requested Advance by an amount equal to such withdrawn portion in respect of each Advance Notice; provided that in the event of any such automatic withdrawal and automatic modification, Investor will promptly notify the Company of such event.

(d)Minimum Acceptable Price.

(i)With respect to each Advance Notice, the Company may notify the Investor of the MAP with respect to such Advance by indicating a MAP on such Advance Notice. If no MAP is specified in an Advance Notice, then no MAP shall be in effect in connection with such Advance. Each Trading Day during a Pricing Period for which (A) with respect to each Advance Notice with a MAP, the VWAP of the Common Shares is below the MAP in effect with respect to such Advance Notice, or (B) there is no VWAP (each such day, an “Excluded Day”), shall result in an automatic reduction to the amount of the Advance set forth in such Advance Notice by one-third (the resulting amount of each Advance being the “Adjusted Advance Amount”), and each Excluded Day shall be excluded from the Pricing Period for purposes of determining the Market Price.

(ii)The total Shares in respect of each Advance (after reductions have been made to arrive at the Adjusted Advance Amount) shall be automatically increased by such number of Common Shares (the “Additional Shares”) equal to the number of Common Shares sold by the Investor on such Excluded Day, if any, and the price paid per share for each Additional Share shall be equal to the MAP in effect with respect to such Advance Notice

A-5

(without any further discount), provided that this increase shall not cause the total Advance to exceed the amount set forth in the original Advance Notice or any limitations set forth in Section 2.01(c).

(e)Notwithstanding any other provision in this Agreement, the Company and the Investor acknowledge and agree that upon the Investor’s receipt of a valid Advance Notice the parties shall be deemed to have entered into an unconditional contract binding on both parties for the purchase and sale of Shares pursuant to such Advance Notice in accordance with the terms of this Agreement and (i) subject to Applicable Law and (ii) subject to Section 3.08 (Trading Activities), the Investor may sell Common Shares during the Pricing Period.

Section 2.02    Closings. The closing of each Advance and each sale and purchase of Shares related to each Advance (each, a “Closing”) shall take place as soon as practicable on or after each Advance Date in accordance with the procedures set forth below. The parties acknowledge that the Purchase Price is not known at the time the Advance Notice is delivered (at which time the Investor is irrevocably bound) but shall be determined on each Closing based on the daily prices of the Common Shares that are the inputs to the determination of the Purchase Price as set forth further below. In connection with each Closing, the Company and the Investor shall fulfill each of its obligations as set forth below:

(a)On each Advance Date, the Investor shall deliver to the Company a written document, in the form attached hereto as Exhibit B (each a “Settlement Document”), setting forth the final number of Shares to be purchased by the Investor (taking into account any adjustments pursuant to Section 2.01), the Market Price, the Purchase Price, the aggregate proceeds to be paid by the Investor to the Company, and a report by Bloomberg, L.P. indicating the VWAP for each of the Trading Days during the Pricing Period (or, if not reported on Bloomberg, L.P., another reporting service reasonably agreed to by the parties), in each case in accordance with the terms and conditions of this Agreement.

(b)Promptly after receipt of the Settlement Document with respect to each Advance (and, in any event, not later than one Trading Day after such receipt), the Company will, or will cause its transfer agent to, electronically transfer such number of Shares to be purchased by the Investor (as set forth in the Settlement Document) by crediting the Investor’s account or its designee’s account at the Depository Trust Company through its Deposit Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto, and transmit notification to the Investor that such share transfer has been requested. Promptly upon receipt of such notification, the Investor shall pay to the Company the aggregate purchase price of the Shares (as set forth in the Settlement Document) in cash in immediately available funds to an account designated by the Company in writing and transmit notification to the Company that such funds transfer has been requested. No fractional shares shall be issued, and any fractional amounts shall be rounded to the next higher whole number of shares. To facilitate the transfer of the Common Shares by the Investor, the Common Shares will not bear any restrictive legends so long as there is an effective Registration Statement covering such Common Shares (it being understood and agreed by the Investor that notwithstanding the lack of restrictive legends, the Investor may only sell such Common Shares in compliance with the requirements of the Securities Act (including any applicable prospectus delivery requirements) or pursuant to an available exemption).

(c)On or prior to the Advance Date, each of the Company and the Investor shall deliver to the other all documents, instruments and writings expressly required to be delivered by either of them pursuant to this Agreement in order to implement and effect the transactions contemplated herein.

(d)Notwithstanding anything to the contrary in this Agreement, if on any day during the Pricing Period (i) the Company notifies Investor that a Material Outside Event has occurred, or (ii) the Company notifies the Investor of a Black Out Period, the parties agree that the pending Advance shall end and the final number of Shares to be purchased by the Investor at the Closing for such Advance shall be equal to the number of Common Shares sold by the Investor during the applicable Pricing Period prior to the notification from the Company of a Material Outside Event or Black Out Period.

In consideration of the Company’s execution and delivery of this Agreement, and in addition to all of the Investor’s other obligations under this Agreement, the Investor shall defend, protect, indemnify and hold harmless the Company and all of its officers, directors, shareholders, employees and agents (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) and each person who controls the Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the “Company Indemnitees”) from and against any and all Indemnified Liabilities incurred by the Company Indemnitees or any of them as a result of, or arising out of, or relating to (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Shares as originally filed or in any amendment thereof, or in any related prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Investor will only be liable for written information relating to the Investor furnished to the Company by or on behalf of the Investor specifically for inclusion in the documents referred to in the foregoing indemnity, and will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Investor by or on behalf of the Company specifically for inclusion therein; (b) any misrepresentation or breach of any representation or warranty made by the Investor in this Agreement or any instrument or document contemplated hereby or thereby executed by the Investor; or (c) any breach of any covenant, agreement or obligation of the Investor(s) contained in this Agreement or any other certificate, instrument or document contemplated hereby or thereby executed by the Investor. To the extent that the foregoing undertaking by the Investor may be unenforceable under Applicable Law, the Investor shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities, which is permissible under Applicable Law.

Section 5.03    Notice of Claim. Promptly after receipt by an Investor Indemnitee or Company Indemnitee of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, such Investor Indemnitee or Company Indemnitee, as applicable, shall, if a claim for an Indemnified Liability in respect thereof is to be made against any indemnifying party under this Article V, deliver to the indemnifying party a written notice of the commencement thereof; but the failure to so notify the indemnifying party will not relieve it of liability under this Article V except to the extent the indemnifying party is prejudiced by such failure. The indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually reasonably satisfactory to the indemnifying party and the Investor Indemnitee or Company Indemnitee, as the case may be; provided, however, that an Investor Indemnitee or Company Indemnitee shall have the right to retain its own counsel with the actual and reasonable third party fees and expenses of not more than one counsel for such Investor Indemnitee or Company Indemnitee to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Investor Indemnitee or Company Indemnitee and the indemnifying party would be inappropriate due to actual or potential differing interests between such Investor Indemnitee or Company Indemnitee and any other party represented by such counsel in such proceeding. The Investor Indemnitee or Company Indemnitee shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Investor Indemnitee or Company Indemnitee which relates to such action or claim. The indemnifying party shall keep the Investor Indemnitee or Company Indemnitee reasonably apprised as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Investor Indemnitee or Company Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Investor Indemnitee or Company Indemnitee of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Investor Indemnitee or Company Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The indemnification required by this Article V shall be made by

A-15

periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received and payment therefor is due.

Section 5.04    Remedies. The remedies provided for in this Article V are not exclusive and shall not limit any right or remedy which may be available to any indemnified person at law or equity. The obligations of the parties to indemnify or make contribution under this Article V shall survive expiration or termination of this Agreement for a period of three years. Notwithstanding anything to the contrary under this Agreement or Applicable Law, no party shall be entitled to any indemnification pursuant to this Article V (other than claims for any damages resulting from fraud) until the aggregate amount of all such damages that would otherwise be indemnifiable to such party equals or exceeds $50,000 (the “Basket”), at which time such party shall be entitled to indemnification for the full amount of all damages (including all damages incurred prior to exceeding the Basket).

Section 5.05    Limitation of liability. Notwithstanding the foregoing, no party shall be entitled to recover from the other party for punitive, indirect, incidental or consequential damages.

Article VI.
Covenants of the Company

Section 6.01    Registration Statement.

(a)The Registration Statement. The Company has filed, in accordance with the provisions of the Securities Act and the rules and regulations thereunder, with the SEC a shelf registration statement on Form S-3 (File Number 333-263298) (the “Initial Registration Statement”) including a base prospectus, with respect to the issuance and sale of securities by the Company, including Common Shares, which contains, among other things a Plan of Distribution section disclosing the methods by which the Company may sell the Common Shares. The Initial Registration Statement was declared effective on April 25, 2022 and remains in effect on the date hereof. Except where the context otherwise requires, the Initial Registration Statement, as amended when it became effective, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus subsequently filed with the SEC pursuant to Rule 424(b) under the Securities Act or deemed to be a part of the Initial Registration Statement pursuant to Rule 430B of the Securities Act, is herein called the “Registration Statement.”

(b)Initial Disclosure. Promptly after the date hereof (and prior to the Company delivering an Advance Notice to the Investor hereunder), the Company shall file with the SEC a report on Form 8-K or such other appropriate form as determined by counsel to the Company, relating to the transactions contemplated by this Agreement and a preliminary Prospectus Supplement pursuant to Rule 424(b) of the Securities Act disclosing all information relating to the transaction contemplated hereby required to be disclosed therein and an updated Plan of Distribution, including, without limitation, the name of the Investor, the number of Shares being offered hereunder, the terms of the offering, the purchase price of the Shares, and other material terms of the offering, and any other information or disclosure necessary to register the transactions contemplated herein (collectively, the “Initial Disclosure”) and shall provide the Investor with 24 hours to review the Initial Disclosure prior to its filing. Promptly, and in any event no later than two days after each Advance Date, the Company shall file with the SEC a Prospectus Supplement pursuant to Rule 424(b) of the Securities Act disclosing all information relating to the particular Advance to be disclosed therein, including, without limitation, the number of Shares offered and the purchase price of the Shares, and other material terms of the particular offering, and any other information or disclosure necessary to register the Shares issued pursuant to such Advance.

(c)Maintaining a Registration Statement. The Company shall use commercially reasonable efforts to maintain the effectiveness of any Registration Statement with respect to the Shares at all times during the Commitment Period, provided, however, that the Company shall be under no further obligation to maintain the effectiveness of the Registration Statement to the extent permitted pursuant to Section 2.04. Notwithstanding anything to the contrary contained in this Agreement, the Company shall ensure that, when filed, each Registration Statement (including, without limitation, all amendments and supplements

A-16

thereto) and the prospectus (including, without limitation, all amendments and supplements thereto) used in connection with such Registration Statement shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading. During the Commitment Period, the Company shall notify the Investor promptly if (i) the Registration Statement shall cease to be effective under the Securities Act, (ii) the Common Shares shall cease to be authorized for listing on the Principal Market, (iii) the Common Shares cease to be registered under Section 12(b) or Section 12(g) of the Exchange Act or (iv) the Company fails to file in a timely manner all reports and other documents required of it as a reporting company under the Exchange Act.

(d)Filing Procedures. Not less than one business day prior to the filing of a Registration Statement and not less than one business day prior to the filing of any related amendments and supplements to any Registration Statement (except for any amendments or supplements caused by the filing of any annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and any similar or successor reports), the Company shall furnish to the Investor copies of all such documents proposed to be filed, which documents (other than those filed pursuant to Rule 424 promulgated under the Securities Act) will be subject to the reasonable and prompt review of the Investor (in each of which cases, if such document contains material non-public information as consented to by the Investor pursuant to Section 6.13, the information provided to Investor will be kept strictly confidential until filed and treated as subject to Section 6.08). The Investor shall furnish comments on a Registration Statement and any related amendment and supplement to a Registration Statement to the Company within 24 hours of the receipt thereof. If the Investor fails to provide comments to the Company within such 24-hour period, then the Registration Statement, related amendment or related supplement, as applicable, shall be deemed accepted by the Investor in the form originally delivered by the Company to the Investor.

(e)Delivery of Final Documents. The Company shall furnish to the Investor without charge, (i) at least one copy of each Registration Statement as declared effective by the SEC and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, all exhibits and each preliminary prospectus, (ii) at the request of the Investor, at least one copy of the final prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as the Investor may reasonably request) and (iii) such other documents as the Investor may reasonably request from time to time in order to facilitate the disposition of the Common Shares owned by the Investor pursuant to a Registration Statement. Filing of the forgoing with the SEC via its EDGAR system shall satisfy the requirements of this section.

(f)Amendments and Other Filings. The Company shall (i) prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the related prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act, as may be necessary to keep such Registration Statement effective at all times during the Commitment Period.

(g)Blue-Sky. The Company shall use its commercially reasonable efforts to, if required by Applicable Law, (i) register and qualify the Common Shares covered by a Registration Statement under such other securities or “blue sky” laws of such jurisdictions in the United States as the Investor reasonably requests, (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Commitment Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Commitment Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Common Shares for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (w) make any change to its Articles of Incorporation or Bylaws, (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 6.01(f), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify the Investor of the receipt by the Company of any

A-17

notification with respect to the suspension of the registration or qualification of any of the Common Shares for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

Section 6.02    Suspension of Registration Statement.

(a)Establishment of a Black Out Period. During the Commitment Period, the Company from time to time may suspend the use of the Registration Statement by written notice to the Investor in the event that the Company determines in its sole discretion in good faith that such suspension is necessary to (A) delay the disclosure of material nonpublic information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company or (B) amend or supplement the Registration Statement or prospectus so that such Registration Statement or prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (a “Black Out Period”).

(b)No Sales by Investor During the Black Out Period. During such Black Out Period, the Investor agrees not to sell any Common Shares of the Company.

(c)Limitations on the Black Out Period. The Company shall not impose any Black Out Period that is longer than 60 days or in a manner that is more restrictive (including, without limitation, as to duration) than the comparable restrictions that the Company may impose on transfers of the Company’s equity securities by its directors and senior executive officers. In addition, the Company shall not deliver any Advance Notice during any Black Out Period. If the public announcement of such material, nonpublic information is made during a Black Out Period, the Black Out Period shall terminate immediately after such announcement, and the Company shall immediately notify the Investor of the termination of the Black Out Period.

Section 6.03    Listing of Common Shares. As of each Advance Date, the Shares to be sold by the Company from time to time hereunder will have been registered under Section 12(b) of the Exchange Act and approved for listing on the Principal Market, subject to official notice of issuance.

Section 6.05    Exchange Act Registration. The Company will file in a timely manner all reports and other documents required of it as a reporting company under the Exchange Act and will not take any action or file any document (whether or not permitted by Exchange Act or the rules thereunder) to terminate or suspend its reporting and filing obligations under the Exchange Act.

Section 6.06    Transfer Agent Instructions. For any time while there is a Registration Statement in effect for this transaction, the Company shall (if required by the transfer agent for the Common Shares) cause legal counsel for the Company to deliver to the transfer agent for the Common Shares (with a copy to the Investor) instructions to issue Common Shares to the Investor free of restrictive legends upon each Advance if the delivery of such instructions are consistent with Applicable Law.

Section 6.07    Corporate Existence. The Company will use commercially reasonable efforts to preserve and continue the corporate existence of the Company during the Commitment Period.

Section 6.08    Notice of Certain Events Affecting Registration; Suspension of Right to Make an Advance.

A-18

for additional information by the SEC or any other Federal or state governmental authority during the period of effectiveness of the Registration Statement or any request for amendments or supplements to the Registration Statement or related prospectus; (ii) the issuance by the SEC or any other Federal governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) receipt of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Common Shares for sale in any jurisdiction or the initiation or written threat of any proceeding for such purpose; (iv) the happening of any event that makes any statement made in the Registration Statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, related prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the related prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or of the necessity to amend the Registration Statement or supplement a related prospectus to comply with the Securities Act or any other law; and (v) the Company’s reasonable determination that a post-effective amendment to the Registration Statement would be appropriate; and the Company will promptly make available to the Investor any such supplement or amendment to the related prospectus. The Company shall not deliver to the Investor any Advance Notice, and the Company shall not sell any Shares pursuant to any pending Advance Notice (other than as required pursuant to Section 2.02(d)), during the continuation of any of the foregoing events (each of the events described in the immediately preceding clauses (i) through (v), inclusive, a “Material Outside Event”).

Section 6.09    Consolidation. If an Advance Notice has been delivered to the Investor, then the Company shall not effect any consolidation of the Company with or into, or a transfer of all or substantially all the assets of the Company to another entity before the transaction contemplated in such Advance Notice has been closed in accordance with Section 2.02 hereof, and all Shares in connection with such Advance have been received by the Investor.
