Item 5.03 Amendment to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On January 30, 2026, BioAtla, Inc. (the “Company” or “BioAtla”) filed a Certificate of Elimination (the “Certificate of Elimination”) with the Secretary of State of the State of Delaware with respect to the Company’s Series A Junior Preferred Stock, par value $0.0001 per share (the “Series A Junior Preferred Stock”), following the redemption of the one (1) issued and outstanding share of Series A Junior Preferred Stock (the “Series A Preferred Share”). The Certificate of Elimination eliminated from the Company’s Amended and Restated Certificate of Incorporation all matters set forth in the Certificate of Designation of Series A Junior Preferred Stock, filed with the Secretary of State of the State of Delaware on January 9, 2026, with respect to the Series A Junior Preferred Stock.

The foregoing description of the Certificate of Elimination does not purport to be complete and is qualified in its entirety by reference to the text of the Certificate of Elimination, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 5.07. Submission of Matters to a Vote of Security Holders.

As previously disclosed, on December 30, 2025, the Company originally convened a special meeting of stockholders (the “Special Meeting”). The Special Meeting was held to consider the following proposals: (1) the potential issuance of 20% or more of the aggregate number of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), issued and outstanding as of November 20, 2025, pursuant to the Pre-Paid Advance Agreements, dated November 20, 2025, by and between the Company and each of YA II PN, Ltd., a Cayman Islands exempt limited company (“Yorkville”), Anson Investments Master Fund LP and Anson East Master Fund LP, and the Standby Equity Purchase Agreement, dated November 20, 2025, by and between the Company and Yorkville, pursuant to Nasdaq Listing Rule 5635(d) (the “Stock Issuance Proposal”); (2) an amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended, to, at the discretion of the Board, effect a reverse stock split with respect to the Common Stock at any time prior to June 30, 2026, at a ratio of 1-for-5 to 1-for-20 (the “Range”), with the ratio within such Range to be determined at the discretion of the Board without further approval or authorization of the Company’s stockholders (the “Reverse Stock Split Proposal”); and (3) the adjournment or adjournments of the Special Meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes in favor of the Stock Issuance Proposal or the Reverse Stock Split Proposal (the “Adjournment Proposal”). The Company’s Amended and Restated Certificate of Incorporation requires the affirmative vote of two-thirds (2/3) of the voting power of the Company’s outstanding shares entitled to vote thereon to approve the Reverse Stock Proposal. At the time of the originally convened Special Meeting on December 30, 2025, the stockholders approved the Stock Issuance Proposal and the Adjournment Proposal, but consistent with the low rates of participation and voting by the Company’s retail stockholder base, and although more than 70% of the shares represented by proxies received by the Company authorized the proxyholders to vote “FOR” the Reverse Stock Split Proposal, there were insufficient votes to approve the Reverse Stock Split Proposal, and the Company determined to adjourn the Special Meeting to January 12, 2026 for the purpose of soliciting additional proxies with respect to the Reverse Stock Split Proposal.

At the reconvened Special Meeting on January 12, 2026, consistent with the low rates of participation and voting by the Company’s retail stockholder base, and although more than 70% of the shares represented by proxies received by the Company authorized the proxyholders to vote “FOR” the Reverse Stock Split Proposal, there were still insufficient votes to approve the Reverse Stock Split Proposal. Based upon, among other things, the reasons the Board previously considered in declaring the Reverse Stock Split Proposal advisable, and the fact that more than 70% of the shares represented by proxies received by the Company have authorized the proxyholders to vote “FOR” the Reverse Stock Split Proposal, the Board authorized (i) authorized an adjournment of the reconvened Special Meeting to January 26, 2026 (the “Reconvened Special Meeting”), (ii) authorized and issued one (1) share of a new series of the Company’s preferred stock, par value $0.0001 per share, designated as “Series A Junior Preferred Stock,” entitling the holder thereof to a number of votes that would enable the approval of the Reverse Stock Split Proposal if the holders of at least two-thirds (2/3) of the voting power of the Common Stock present in person or by proxy at the Reconvened Special Meeting and entitled to vote thereon vote “FOR” the Reverse Stock Split Proposal, and (iii) fixed a new record date of the close of business on January 12, 2026 (the “New Record Date”) for determining the stockholders entitled to vote at the Reconvened Special Meeting that was after the issuance of the aforementioned Series A Junior Preferred Stock.

Present at the Reconvened Special Meeting, in person or by proxy, were holders of 44,661,262 shares of Common Stock and one (1) Series A Junior Preferred Stock, as of the New Record Date, representing at least a majority of the voting power of the shares of the capital stock entitled to vote at the Reconvened Special Meeting as of the New Record Date, which constituted a quorum. As previously disclosed, the Series A Junior Preferred Stock entitles the holder thereof to cast on the Reverse Stock Split Proposal and any other voting proposal set forth in the Certificate of Designation of Series A Junior Preferred Stock (the “Certificate of Designation”), a number of votes equal to 64,040,396 votes (the number of shares of Common Stock outstanding on the New Record Date, provided that the holder of the Series A Junior Preferred Stock is required to cast all votes “for” the Reverse Stock Split Proposal if at least two-thirds (2/3) of the voting power of the Common Stock present and entitled to vote thereon approve the proposal, and “against” the Reverse Stock Split Proposal if less than two-thirds (2/3) of the voting power of the Common Stock present and entitled to vote approve such Reverse Stock

Split Proposal. Since over 80% of the proxies received by the Company included instructions to vote “FOR” the Reverse Stock Split Proposal, the holder of the Series A Junior Preferred Stock cast all votes “FOR” the Reverse Stock Split Proposal at the Reconvened Special Meeting.

The voting results with respect to the Reverse Stock Split Proposal, including 64,040,396 votes represented by the Series A Junior Preferred Stock, were as follows:


	Votes For	Votes Against	Abstentions	Broker Non-Votes
Common Stock	36,182,696	8,290,601	187,965	0
Series A Junior Preferred Stock	64,040,396	0	0	0
Total Votes	100,223,092	8,290,601	187,965	0

On January 30, 2026, the Company redeemed the one (1) share of Series A Junior Preferred Stock for $0.01. In addition, the Board determined to exercise its discretion not to implement a reverse stock split while the Company is listed on The Nasdaq Stock Market (“Nasdaq”) based upon, among other considerations, its ongoing discussions with Nasdaq since January 13, 2026. In these ongoing discussions with Nasdaq, the Company was informed for the first time that if the Company were to implement a reverse stock split that was approved by the Company’s stockholders with the Series A Preferred Share, it would likely be cited for a violation of Nasdaq Listing Rule 5640 (the “Voting Rights Rule”). As part of these ongoing discussions, Nasdaq informed the Company that, although Nasdaq historically has approved widespread use of grants of super-voting preferred stock (such as the Series A Preferred Share) to approve reverse stock splits and has publicly stated such use is consistent with the Voting Rights Rule, Nasdaq has internally determined that such use of super-voting preferred is now no longer permitted. Nasdaq has acknowledged to the Company that there is no public notice of this change in position. While the Company believes that obtaining the approval of stockholders with the Series A Preferred Share complies with the Voting Rights Rule and is in compliance with Nasdaq’s policy as set forth in its Staff Interpretative Letter issued in 2022 (the “2022 Guidance”), Nasdaq informed the Company that the unannounced removal of the 2022 Guidance from its website, even though without any public announcement, constituted a rescission of the 2022 Guidance. Based upon, among other things, (i) the reasons the Board previously considered in declaring the Reverse Stock Split Proposal advisable, (ii) the fact that a majority of the outstanding shares of Common Stock were voted “FOR” the Reverse Stock Split Proposal, (iii) the fact that, but for Nasdaq’s recent non-public determination that the 2022 Guidance is now rescinded, the Company could have implemented the Reverse Stock Split Proposal without violating Nasdaq Rule 5640, and (iv) that a violation of the Voting Rights Rule would result in a delisting from Nasdaq, and could bar the Company from re-listing on Nasdaq, the New York Stock Exchange, or other national securities exchange, the Board has determined it is advisable to effect an alternative transaction through a merger of the Company with a wholly owned subsidiary as described below to implement a similar reduction in the number of outstanding shares as the Reverse Stock Split Proposal.

On January 30, 2026, the Company entered into the Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which (i) a wholly owned subsidiary (the “Merger Sub”) will merge with and into the Company, with the Company surviving (the “Merger”), (ii) every fifty (50) shares of Common Stock issued and outstanding, or held as treasury stock, will be converted into one (1) share of common stock of the surviving corporation, which shall be the Company, and (iii) the Company’s Amended and Restated Certificate of Incorporation would be amended and restated to, among other things, exempt future amendments to Article IV thereof from the supermajority voting requirements of Article IX and instead default to the voting requirements provided by Delaware law. Under Delaware law and the Company’s Amended and Restated Certificate of Incorporation, the Merger Agreement must be approved by the holders of a majority of the outstanding shares of Common Stock. The Board has set the close of business on February 2, 2026, as the record date for the determination of stockholders of the Company entitled to vote to adopt and approve the Merger Agreement at a special meeting to be held virtually at a date and time to be noticed to the Company’s stockholders pursuant to the Company’s Amended and Restated Bylaws.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the Merger Agreement, a copy of which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 7.01 Regulation FD.

As previously disclosed, on December 30, 2025, BioAtla entered into an Investment Agreement (the “Investment Agreement”) with Inversagen AI, LLC, a Delaware limited liability company (“Inversagen AI”), and Alliance International Resources Corp., a Nevada corporation (“AIRC”). Subject to completion of financings by Inversagen AI as set forth in the Investment Agreement, with the initial investment into Inversagen AI being led by AIRC, BioAtla agreed to sell common units of a wholly owned subsidiary, BA 3021 SPV LLC, a Delaware limited liability company (the “SPV”) to Inversagen AI in a private placement over multiple closings.

On January 29, 2026, the Company received confirmation from AIRC that AIRC will complete its investment in Inversagen AI, and subject to completion of such investment, Inversagen AI will pay $5 million to BioAtla for the purchase of common units of the SPV that represent 4.375% of the SPV common units.

On January 16, 2026, the Company filed a Form S-3 shelf registration with the Securities and Exchange Commission (“SEC”) to replace its expiring universal shelf registration statement that expired on January 17, 2026. In accordance with SEC rules, the Company may make securities offerings under the existing shelf registration statement until the new registration statement is declared effective, subject to a maximum extension of 180 days and subject to continued S-3 eligibility. The renewal maintains continuous flexibility for the Company. To satisfy the Company's obligations pursuant to the Pre-Paid Advance Agreements and Standby Equity Purchase Agreement, the Form S-3 registration statement, once declared effective by the SEC, will also register the offering and sale of common stock pursuant to the Pre-Paid Advance Agreements and the Standby Equity Purchase Agreement dated November 20, 2026 by and between the Company and certain investors named therein. Other than the conversion of the remaining principal aggregate amount outstanding under the Pre-Paid Advance Agreements at the option of the investors, there are no specific plans to offer securities under the shelf registration statement at this time.

The information included in this Item 7.01 is being furnished and shall not be deemed to be “filed” for the purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference into any registration statement or other document filed pursuant to the Securities Act, except as shall be expressly set forth by specific reference in such filing.

Item 8.01 Other Events

As previously reported, on August 6, 2025, the Company was formally notified by the Nasdaq Listing Qualifications Staff (the “Staff”) that the Company no longer satisfied the $1.00 bid price requirement and the $10 million stockholders’ equity requirement (or the alternative standards of $50 million in market value of listed securities (“MVLS”) or $50 million in total assets and $50 million in total revenue) for continued listing on The Nasdaq Global Market under Nasdaq Listing Rule 5450.

In response, the Company requested a hearing before the Nasdaq Hearings Panel (the “Panel”), at which the Company presented its plan to evidence compliance with all applicable criteria for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550, including the $1.00 bid price requirement (the “Bid Price Rule”) and the $2.5 million stockholders’ equity requirement (the “Equity Rule”), the alternatives to which are $35 million in MVLS (the “MVLS Rule”) or $500,000 in net income (and, together, the “Equity/MVLS Rule”). On September 16, 2025, the Panel granted the Company’s request for continued listing (the “Panel Decision”), subject to the Company’s timely submission of an application to transfer its listing to The Nasdaq Capital Market, and the Company’s compliance with the Equity Rule and the Bid Price Rule by December 31, 2025, and February 2, 2026, respectively.

In accordance with Nasdaq Listing Rule 5810(c)(3)(H) (the “Discretionary Monitor Rule”), “compliance with [the price-based listing criteria] is generally achieved by meeting the requirement for a minimum of ten consecutive business days.” Under the rule, the “Staff may, in its discretion, require a Company to satisfy the applicable Price-based Requirement for a period in excess of ten consecutive business days, but generally no more than 20 consecutive business days, before determining that the Company has demonstrated an ability to maintain long-term compliance. In determining whether to require a Company to meet the applicable Price-based-requirement beyond ten business days, Staff may consider all relevant facts and circumstances, including without limitation: (i) the margin of compliance (the amount by which a Company exceeds the applicable Price-based Requirement); (ii) the trading volume (a lack of trading volume may indicate a lack of bona fide market interest in the security at the posted bid price); (iii) the Market Maker montage (the number of Market Makers quoting at or above $1.00 or the minimum price necessary to satisfy another Price-based Requirement; and the size of their quotes); and (iv) the trend of the security price (is it up or down).”

Beginning September 24, 2025, through the close of business on December 31, 2025 (the deadline for compliance with the Equity Rule as set forth in the Panel Decision), the Company evidenced a minimum $35 million MVLS for 64 consecutive trading days, ranging from a low MVLS of $36.03 million to a high MVLS of $71.73 million. Having evidenced compliance with the MVLS Rule for 57 consecutive business days as of December 18, 2026, on December 19, 2025, the Company requested that Nasdaq issue a determination that the Company had regained compliance with the MVLS Rule as an alternative to the Equity Rule.

Notwithstanding the foregoing, more than three weeks later on January 13, 2026, Nasdaq denied the Company’s request for a compliance determination given that the Company no longer satisfied the MVLS Rule (or the alternative Equity Rule) as of that date. Nasdaq provided the Company with the opportunity to update its plan to evidence compliance with either the Equity/MVLS Rule, which update the Company submitted on January 20, 2026. Nasdaq notified the Company on January 27, 2026, that the Panel had granted the Company an extension through February 2, 2026 to evidence compliance with all applicable criteria for continued listing on The Nasdaq Capital Market.

The Company believes Nasdaq’s apparent inaction and unwillingness to issue a compliance determination in this matter was in error and represents a serious misapplication of the Nasdaq Listing Rules to the Company. As referenced above, the Discretionary Monitor Rule states that “compliance is generally achieved by meeting the requirement for a minimum of ten consecutive business days” although the Staff may, in its discretion, require a Company to satisfy the applicable requirement for more than ten consecutive business days, “but generally no more than 20 consecutive business days,” which the Company far exceeded, and with such exercise of discretion based upon an analysis of certain enumerated criteria, which does not appear to have occurred here. The Company believes that Nasdaq’s delay in the consideration and confirmation of the Company’s compliance status, its subsequent failure to issue a determination that the Company had regained compliance with the MVLS Rule, as well as Nasdaq’s recent decision to overturn longstanding Nasdaq policy regarding the use of super-voting stock to achieve quorum and thereby seek to obtain shareholder approval for a reverse stock split, has and will cause the Company irreparable harm.

In the event that the Company is unable to regain compliance with the Bid Price Rule and the Equity/MVLS Rule by February 2, 2026, the Company’s securities will be subject to suspension and delisting from Nasdaq. Following receipt of a delist determination, the Company may, with 15 calendar days, request an appeal of the delist determination to the Nasdaq Listing and Hearing Review Council (the “Council”) or the Council may call for review the delist determination within 45 calendar days of issuance. A timely request for an appeal or review by the Council will not stay the suspension of trading in the Company’s common stock on Nasdaq unless a call for review determination by the Council specifies to the contrary. The Company intends to request that the Council call for review any decision by the Panel to delist the Company. The Company can provide no assurance, however, that a review by the Council will result in the continued listing of its shares of Common Stock or in the event of a suspension or delisting, a re-instatement of trading of the Company’s Common Stock on Nasdaq. If trading in the Company’s Common Stock is suspended on Nasdaq, the Company should be eligible to trade on the OTC Markets system, which may have a material adverse effect on the trading price and volume for the Common Stock, and the Company’s stockholders may find it more difficult to sell their shares.

Exhibit 1.1

Agreement and Plan of Merger

This Agreement and Plan of Merger (this “Agreement”) is made and entered into as of January 30, 2026, by and between BioAtla, Inc., a Delaware corporation (the “Company”), and BA Merger Sub, Inc., a Delaware corporation (“Merger Sub” and, together with the Company, the “Constituent Corporations”).

Whereas, the Board of Directors of each of the Constituent Corporations deems it advisable and in the best interests of each of the Constituent Corporations that Merger Sub be merged with and into the Company (hereinafter, in such capacity, sometimes referred to as the “Surviving Corporation”) as permitted by the Delaware General Corporation Law (the “DGCL”) pursuant to the terms hereinafter set forth;

(b) At the Effective Time, each share of capital stock of Merger Sub issued and outstanding as of immediately before the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

Section 5. Certificate of Incorporation of the Surviving Corporation. From and after the Effective Time, the Certificate of Incorporation of the Company shall be amended and restated in its entirety to take the form set forth on Exhibit A hereto.

Section 6. Bylaws of the Surviving Corporation. The Bylaws of Company shall be unaffected by the Merger and shall be the Bylaws of the Surviving Corporation.

(c) this Agreement shall have been adopted by (i) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of common stock of the

Company, and (ii) the affirmative vote of the sole stockholder of Merger Sub (collectively, the “Required Stockholder Approval”).

The powers, preferences and rights of, and the qualifications, limitations and restrictions upon, each class or series of stock shall be determined in accordance with, or as set forth below in, this Article IV.

A. COMMON STOCK

Subject to all the rights, powers and preferences of the Undesignated Preferred Stock and except as provided by law or in this Certificate (or in any certificate of designations of any series of Undesignated Preferred Stock):

(a) the holders of the Common Stock shall have the exclusive right to vote for the election of directors of the Corporation (the “Directors”) and on all other matters requiring stockholder action, each outstanding share entitling the holder thereof to one vote on each matter properly submitted to the stockholders of the Corporation for their vote; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (or on any amendment to a certificate of designations of any series of Undesignated Preferred Stock) that alters or changes the powers, preferences, rights or other terms of one or more outstanding series of Undesignated Preferred Stock if the holders of such affected series of Undesignated Preferred Stock are entitled to vote, either separately or together with the holders of one or more other such series, on such amendment pursuant to this Certificate (or pursuant to a certificate of designations of any series of Undesignated Preferred Stock) or pursuant to the DGCL;

(b) dividends may be declared and paid or set apart for payment upon the Common Stock out of any assets or funds of the Corporation legally available for the payment of dividends, but only when and as declared by the Board of Directors or any authorized committee thereof; and

(c) upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the net assets of the Corporation shall be distributed pro rata to the holders of the Common Stock, treated equally and identically, subject to any preferential or other rights of any then outstanding Undesignated Preferred Stock.

B. UNDESIGNATED PREFERRED STOCK

The Board of Directors or any authorized committee thereof is expressly authorized, to the fullest extent permitted by law, to provide by resolution or resolutions for, out of the unissued shares of Undesignated Preferred Stock, the issuance of the shares of Undesignated Preferred Stock in one or more series of such stock, and by filing a certificate of designations pursuant to applicable law of the State of Delaware, to establish or increase or decrease from time to time the number of shares of each such series (but not below the number of shares of such series then outstanding), and to fix the designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series and any qualifications, limitations and restrictions thereof.

ARTICLE V

STOCKHOLDER ACTION

1. Action without Meeting. Any action required or permitted to be taken by the stockholders of the Corporation at any annual or special meeting of stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders and may not be taken or effected by a written consent of stockholders in lieu thereof. Notwithstanding

anything herein to the contrary, the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of capital stock entitled to vote thereon, and the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of each class entitled to vote thereon as a class, shall be required to amend or repeal any provision of this Article V, Section 1.

2. Special Meetings. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the chairman of the Board of Directors, the Corporation’s chief executive officer or the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office, and special meetings of stockholders may not be called by any other person or persons. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation.

ARTICLE VI

DIRECTORS

1. General. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors except as otherwise provided herein or required by law.

2. Election of Directors. Election of Directors need not be by written ballot unless the Amended and Restated Bylaws of the Corporation (the “Bylaws”) shall so provide.

3. Number of Directors; Term of Office. The number of Directors of the Corporation shall be fixed solely and exclusively by resolution duly adopted from time to time by the Board of Directors. The Directors, other than those who may be elected by the holders of any series of Undesignated Preferred Stock, shall be classified, with respect to the term for which they severally hold office, into three classes, designated as Class I, Class II and Class III, and each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. The Board of Directors is authorized to assign members of the Board of Directors already in office to Class I, Class II or Class III at the time such classification becomes effective. The initial Class I Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2021, the initial Class II Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2022, and the initial Class III Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2023. At each annual meeting of stockholders, Directors elected to succeed those Directors whose terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election. Notwithstanding the foregoing, the Directors elected to each class shall hold office until their successors are duly elected and qualified or until their earlier resignation, death or removal.

Notwithstanding the foregoing, whenever, pursuant to the provisions of Article IV of this Certificate, the holders of any one or more series of Undesignated Preferred Stock shall have the right, voting separately as a series or together with holders of other such series, to elect Directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies

and other features of such directorships shall be governed by the terms of this Certificate and any certificate of designations applicable to such series.

Notwithstanding anything herein to the contrary, the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of capital stock entitled to vote thereon, and the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of each class entitled to vote thereon as a class, shall be required to amend or repeal any provision of this Article VI, Section 3.

4. Vacancies. Subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock to elect Directors and to fill vacancies in the Board of Directors relating thereto, any and all vacancies in the Board of Directors, however occurring, including, without limitation, by reason of an increase in the size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely and exclusively by the affirmative vote of a majority of the remaining Directors then in office, even if less than a quorum of the Board of Directors, and not by the stockholders. Any Director appointed in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of Directors in which the new directorship was created or the vacancy occurred and until such Director’s successor shall have been duly elected and qualified or until his or her earlier resignation, death or removal. Subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock to elect Directors, when the number of Directors is increased or decreased, the Board of Directors shall, subject to Article VI, Section 3 hereof, determine the class or classes to which the increased or decreased number of Directors shall be apportioned; provided, however, that no decrease in the number of Directors shall shorten the term of any incumbent Director. In the event of a vacancy in the Board of Directors, the remaining Directors, except as otherwise provided by law, shall exercise the powers of the full Board of Directors until the vacancy is filled.

5. Removal. Subject to the rights, if any, of any series of Undesignated Preferred Stock to elect Directors and to remove any Director whom the holders of any such series have the right to elect, any Director (including persons elected by Directors to fill vacancies in the Board of Directors) may be removed from office (i) only with cause and (ii) only by the affirmative vote of the holders of not less than two-thirds (2/3) of the outstanding shares of capital stock then entitled to vote at an election of Directors. At least forty-five (45) days prior to any annual or special meeting of stockholders at which it is proposed that any Director be removed from office, written notice of such proposed removal and the alleged grounds thereof shall be sent to the Director whose removal will be considered at the meeting.

ARTICLE VII

LIMITATION OF LIABILITY

A Director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as a Director, except for liability (a) for any breach of the Director’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL or (d) for any transaction from which the Director derived an improper personal benefit. If the DGCL is amended after the effective date of this

Certificate to authorize corporate action further eliminating or limiting the personal liability of Directors, then the liability of a Director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Any amendment, repeal or modification of this Article VII by either of (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any right or protection existing at the time of such amendment, repeal or modification with respect to any acts or omissions occurring before such amendment, repeal or modification of a person serving as a Director at the time of such amendment, repeal or modification.

ARTICLE VIII

AMENDMENT OF BYLAWS

1. Amendment by Directors. Except as otherwise provided by law, the Bylaws of the Corporation may be amended or repealed by the Board of Directors by the affirmative vote of a majority of the Directors then in office.

2. Amendment by Stockholders. Except as otherwise provided therein, the Bylaws of the Corporation may be amended or repealed at any annual meeting of stockholders, or special meeting of stockholders called for such purpose, by the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of capital stock entitled to vote on such amendment or repeal, voting together as a single class; provided, however, that if the Board of Directors recommends that stockholders approve such amendment or repeal at such meeting of stockholders, such amendment or repeal shall only require the affirmative vote of the majority of the outstanding shares of capital stock entitled to vote on such amendment or repeal, voting together as a single class.

ARTICLE IX

AMENDMENT OF CERTIFICATE OF INCORPORATION

The Corporation reserves the right to amend or repeal this Certificate in the manner now or hereafter prescribed by statute and this Certificate, and all rights conferred upon stockholders herein are granted subject to this reservation. Except as otherwise required by this Certificate or by law, whenever any vote of the holders of capital stock of the Corporation is required to amend or repeal any provision of this Certificate (other than Article IV), such amendment or repeal shall require the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of capital stock entitled to vote on such amendment or repeal, and the affirmative vote of not less than two-thirds (2/3) of the outstanding shares of each class entitled to vote thereon as a class, at a duly constituted meeting of stockholders called expressly for such purpose; provided, however, that notwithstanding anything to the contrary herein, and for the avoidance of doubt, the Corporation expressly elects to be governed by Section 242(d) of the DGCL.

ARTICLE X

CONSENT TO JURISDICTION

1. Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware does not have jurisdiction, the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) any action asserting a claim arising pursuant to any provision of this Certificate or the Bylaws of the Corporation (in each case, as they may be amended from time to time) or governed by the internal affairs doctrine. This Article X, Section 1 does not apply to claims arising under the Securities Act of 1933 or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

2. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any claims arising under the Securities Act of 1933.

3. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article X.
