Overview

As previously announced, Terrestrial Energy Inc. (“New Terrestrial Energy”) (formerly known as HCM II Acquisition Corp., or “HCM II”), a Delaware corporation (prior to the Domestication, a Cayman Islands exempted company), entered into that certain Business Combination Agreement, dated as of March 26, 2025 (as amended from time to time, the “Business Combination Agreement”), by and among HCM II, Terrestrial Energy Development Inc., a Delaware corporation (formerly known as Terrestrial Energy Inc., or “LegacyTerrestrial Energy”), and HCM II Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of HCM II (“MergerSub”), pursuant to which: (1) at the closing of the transactions contemplated by the Business Combination Agreement (the “Closing”) and following the Domestication (as defined below), Merger Sub merged with and into Legacy Terrestrial Energy (the “Merger”), with Legacy Terrestrial Energy surviving as a wholly owned subsidiary of New Terrestrial Energy, resulting in a combined company whereby New Terrestrial Energy became the sole stockholder of Legacy Terrestrial Energy, as more fully described in the definitive proxy statement and final prospectus of HCM II, dated September 26, 2025 (the “Proxy Statement/Prospectus”), which was filed with the SEC; (2) HCM II domesticated (the “Domestication”) as a Delaware corporation in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), the Companies Act (As Revised) of the Cayman Islands (the “CompaniesAct”) and the amended and restated memorandum and articles of association of HCM II (as amended from time to time, the “CaymanConstitutional Documents”); and (3) the other transactions contemplated by the Business Combination Agreement and documents related thereto were consummated (such transactions, together with the Merger and the Domestication, the “Transactions”).

An extraordinary general meeting of HCM II shareholders was held on October 20, 2025 (the “Extraordinary General Meeting”), where the HCM II shareholders considered and approved, among other matters, a proposal to approve the Business Combination Agreement and the Transactions. In connection with the Extraordinary General Meeting, holders of 7,390 HCM II Class A Ordinary Shares (as defined below) exercised their right to redeem their shares for cash at a redemption price of $10.54 per share (the “Redemption Price”), for an aggregate redemption amount of approximately $77,890 (the “Redemption”).

On October 23, 2025, as contemplated by the Business Combination Agreement and described in the section titled “The Domestication Proposal” of the Proxy Statement/Prospectus, HCM II filed a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and filed a certificate of incorporation (the “Certificate of Incorporation”) and a certificate of corporate domestication with the Secretary of State of the State of Delaware, pursuant to which HCM II was domesticated and continued as a Delaware corporation.

Immediately prior to the Domestication, pursuant to the Cayman Constitutional Documents and the Sponsor Support Agreement dated March 26, 2025, among HCM II and Legacy Terrestrial Energy, each of the then issued and outstanding Class B ordinary shares of HCM II, par value $0.0001 per share (each, a “HCMII Class B Ordinary Share”), converted automatically, on a one-for-one basis, into one (1) Class A ordinary share of HCM II, par value $0.0001 per share (each, a “HCM II Class A Ordinary Share” and together with the HCM II Class B Ordinary Shares, the “HCM II Ordinary Shares) (the “Sponsor Share Conversion”). In connection with the Domestication: (i) each then issued and outstanding HCM II Class A Ordinary Share (that was not redeemed pursuant to the Redemption) converted automatically, on a one-for-one basis, into one (1) share of common stock, par value $0.0001 per share, of New Terrestrial Energy (each a “NewTerrestrial Common Share” and collectively, the “New Terrestrial Common Shares”); (ii) each of the then issued and outstanding warrants representing the right to purchase one HCM II Class A Ordinary Share (each an “HCM II Warrant”) converted automatically into a warrant to acquire one (1) New Terrestrial Common Share (each a “New Terrestrial Warrant”); and (iii) each of the then issued and outstanding HCM II Units (as defined in the Proxy Statement/Prospectus) was cancelled and each holder thereof became entitled to one (1) New Terrestrial Common Share and one-half (1/2) of one New Terrestrial Warrant. No fractional warrants were issued upon such cancellation.

Subject to, and in accordance with the terms and conditions of the Business Combination Agreement, prior to or concurrently with the Effective Time:

i. each<br>share of common stock, par value $0.001, of Legacy Terrestrial Energy (the “Terrestrial Common Shares”) that was issued<br>and outstanding immediately prior to the Effective Time (other than the Excluded Shares (as defined below) and any Dissenting Shares<br>(as defined in the Business Combination Agreement) was cancelled and converted into the right to receive a number of New Terrestrial<br>Common Shares equal to the Exchange Ratio of 44.7029, which was calculated in accordance with the Business Combination Agreement (the<br>“Per Share Base Consideration”);
ii. each<br>share of preferred stock, par value $0.001, of Legacy Terrestrial Energy designated as “Series A Preferred Stock” or “Series<br>A-1 Preferred Stock” that was issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting<br>Shares) was cancelled and converted into the right to receive a number New Terrestrial Common Shares equal to: (A) the number of Terrestrial<br>Common Shares into which such Terrestrial Series A Preferred Shares were converted in accordance with Legacy Terrestrial Energy’s<br>governing documents as of immediately prior to the Effective Time; multiplied by (B) the Per Share Base Consideration;
--- ---
iii. each<br>Terrestrial Common Share and Terrestrial Series A Preferred Share that, immediately prior to the Effective Time, was owned by HCM II<br>or Merger Sub (or any other subsidiary of HCM II), or held by Legacy Terrestrial Energy (in treasury or otherwise), if any (each, an<br>“Excluded Share”), was automatically cancelled and retired without any conversion thereof and ceased to exist, and<br>no consideration was delivered in exchange therefore;
--- ---
iv. each<br>share of preferred stock, par value $0.001 per share, of Legacy Terrestrial Energy previously designated as “Special Voting Preferred<br>Stock” was cancelled and converted into the right to receive one share of preferred stock, par value $0.0001 per share, of New<br>Terrestrial Energy designated as “Special Voting Preferred Stock” pursuant to New Terrestrial Energy’s certificate<br>of incorporation;
--- ---
v. each<br>option to purchase Terrestrial Common Shares (each, a “Terrestrial Option”) that was outstanding and unexercised immediately<br>prior to the Effective Time was automatically assumed by New Terrestrial Energy such that, as of the Effective Time, each share underlying<br>each Terrestrial Option became New Terrestrial Common Shares and the number of such shares were equal to the Exchange Ratio, with such<br>assumption and adjustment completed in a manner intended to satisfy the requirements of Section 409A of the Internal Revenue Code of<br>1986, as amended (the “Code”) and, with respect to any Terrestrial Option that was intended to be an “incentive<br>stock option”, Section 422 of the Code;
--- ---
vi. each warrant to purchase<br> Terrestrial Common Shares or other equity interests of Legacy Terrestrial Energy (each, a “Terrestrial Warrant”)<br> that was outstanding and unexercised immediately prior to the Effective Time was automatically assumed by New Terrestrial Energy and<br> became exercisable, in accordance with the terms and conditions of such Terrestrial Warrant, for the Per Share Base<br> Consideration;
--- ---
vii. Each<br>eight percent (8%) Convertible Note due 2026 issued by Legacy Terrestrial Energy (“Terrestrial Convertible Note”)<br>that was outstanding immediately prior to the Effective Time was cancelled and automatically converted pursuant to its terms, and the<br>holder thereof became entitled to receive, a number of New Terrestrial Common Shares equal to (A) the outstanding amount of such Terrestrial<br>Convertible Note, including any accrued and unpaid interest, divided by (B) seventy-five percent (75%) of the Redemption Price; and
--- ---
viii. Each<br>restricted stock unit (“RSU”) representing the right to receive Terrestrial Common Shares (each, a “TerrestrialRSU”) that was outstanding immediately prior to the Effective Time was automatically assumed by New Terrestrial Energy such<br>that, as of the Effective Time, each share underlying each Terrestrial RSU became New Terrestrial Common Shares and the number of such<br>shares were equal to the Exchange Ratio.

As a result of this review, the Board determined that each of Frederick Buckman, Shawn Matthews, Hugh MacDiarmid, David Hill, William Johnson, Charles Pardee and Robert W. Jones was considered an “independent director” as defined under the Nasdaq listing requirements and rules and the applicable rules of the Exchange Act.

Additional information with respect to the independence of the directors of the Company following the Closing of the Transactions is set forth in the Proxy Statement/Prospectus in the section entitled “Management of New Terrestrial Energy Following the Business CombinationDirector Independence” beginning on page 316, and that information is incorporated by reference herein.

CEO Transaction Bonus


As of October 21, 2025 (the “Grant Date”), Legacy Terrestrial Energy and Mr. Irish entered into a Restricted Stock Unit Agreement (“RSUAgreement”), pursuant to which Mr. Irish was awarded 22,888 RSUs in Legacy Terrestrial Energy. The RSU Agreement was entered into to recognize the efforts of Mr. Irish in furtherance of completion of the Transactions and to incentivize Mr. Irish to remain employed beyond the Closing. Pursuant to the RSU Agreement, 50% of the RSUs will vest on the 12-month anniversary of the Grant Date, and the remaining 50% of the RSUs will vest on the 24-month anniversary of the Grant Date, subject to Mr. Irish’s continued employment through each vesting date; provided that, if Mr. Irish is terminated without “cause” or due to Mr. Irish’s death or disability (each a “Qualifying Termination”), all unvested RSUs will immediately accelerate and become vested as of the date of such Qualifying Termination. In the event that Mr. Irish is terminated as a result of an event that is not a Qualifying Termination, all unvested RSUs held by Mr. Irish pursuant to the RSU Agreement will be automatically forfeited. Vested RSUs will be settled in New Terrestrial Common Shares on or before the 10^th^ business day following the applicable vesting date.

In the event of a “change in control” after the completion of the Transactions, the Board may unilaterally take one or more of the following actions with respect to the RSUs: (i) arrange for the surviving corporation or acquiring corporation to assume or continue the RSU Agreement or substitute a similar stock award; (ii) accelerate the vesting, in whole or in part, of the RSU Agreement; or (iii) cancel or arrange for the cancellation of the RSU Agreement.

A transaction shall not constitute a change in control if its sole purpose is to change the state of New Terrestrial Energy’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held New Terrestrial Energy’s securities immediately before such transaction.

Exhibit 2.4


PLAN OF DOMESTICATION

This PLAN OF DOMESTICATION (the “Plan of Domestication”) is made on October 23, 2025 and sets forth the terms and conditions pursuant to which HCM II Acquisition Corp., a Cayman Islands exempted company (“HCM II”), shall effect a domestication into a Delaware corporation (the “Domestication”) to be known as HCM II Acquisition Corp., pursuant to Sections 265 and 388 of the Delaware General Corporation Law (the “DGCL”).

RECITALS


WHEREAS, HCM II is a Cayman Islands exempted company duly formed and validly existing under the laws of the Cayman Islands;

WHEREAS, the Board of Directors of HCM II (the “Board”) has determined that it is advisable and in the best interests of HCM II that HCM II be converted into and thereafter become, and continue to exist as, a corporation in accordance with Sections 265 and 388 of the DGCL; and

WHEREAS, pursuant to Section 265(h) of the DGCL, the Board has duly approved, authorized, adopted, ratified and confirmed the Domestication pursuant to Sections 265 and 388 of the DGCL.

NOW, THEREFORE, in consideration of the covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, HCM II agrees as follows:

1. Domestication. Upon the Certificate of Domestication and the Certificate of Incorporation becoming effective under Section 103 of the DGCL (the “Effective Time”), HCM II will be converted into a Delaware corporation, pursuant to Sections 265 and 388 of the DGCL, under the name “HCM II Acquisition Corp.” (the “Corporation”) and will, for all purposes of the laws of the State of Delaware, be deemed to be the same entity as HCM II. HCM II will not be required to wind up its affairs or pay its liabilities and distribute its assets, and the Domestication will not be deemed to constitute a dissolution of HCM II and will constitute a continuation of the existence of HCM II in the form of a Delaware corporation.

2. Effective Time. HCM II shall file the Certificate of Domestication, in the form attached hereto as Exhibit A, and the Certificate of Incorporation, in the form attached hereto as Exhibit B (the “Certificate of Incorporation”), with the Secretary of State of the State of Delaware pursuant to Sections 103 and 265 of the DGCL.

3. Conversion of Securities. By virtue of the Domestication:

(a) each of the then issued and outstanding Class A ordinary<br>shares of HCM II will convert automatically, on a one-for-one basis, into a share of common stock of the Corporation having the rights,<br>powers and privileges, and the obligations, set forth in the Certificate of Incorporation;
(b) each of the then issued and outstanding public warrants of<br>HCM II will convert automatically into a public warrant to acquire one share of the Corporation’s common stock, pursuant to the<br>Warrant Agreement, dated August 19, 2024, between HCM II and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant<br>Agreement”);
--- ---
(c) each of the then issued and outstanding private placement<br>warrants of HCM II will convert automatically into a private placement warrant to acquire one share of the Corporation’s common<br>stock, pursuant to the Warrant Agreement; and
--- ---
(d) each of the then issued and outstanding units of HCM II that<br>have not been previously separated into the underlying Class A ordinary shares and underlying public warrants of HCM II upon the request<br>of the holder thereof, will be cancelled and will entitle the holder thereof to one share of common stock of the Corporation and one-half<br>of one public warrant to acquire one share of common stock of the Corporation.
--- ---

4. Tax Matters. For United States federal income tax purposes, the Domestication is intended to qualify as a “reorganization” within the meaning of Section 368(a)(1)(F) of the U.S. Internal Revenue Code of 1986, as amended, and this Plan of Domestication is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a).

5. Governing Documents. (i) At the Effective Time, the Certificate of Incorporation of HCM II (initially filed in accordance with the Companies Law of the Cayman Islands) shall be canceled and the Amended and Restated Memorandum and Articles of Association of HCM II, adopted by special resolution dated as of August 15, 2024 and effective as of August 15, 2024, as may be amended, modified or supplemented, shall be terminated and be of no further force or effect and (ii) from and after the Effective Time, the Certificate of Incorporation, in the form attached hereto as Exhibit B, and the By-Laws of the Corporation, in the form attached hereto as Exhibit C (the “Bylaws”), will govern the affairs of the Corporation and the conduct of its business, until thereafter amended in accordance with the DGCL and their respective terms.

6. Board of Directors. Each member of the Board as of immediately prior to the Effective Time shall be a director of the Corporation from and after the Effective Time, each of whom shall serve as directors of the Corporation until such time as their respective successors have been duly elected and qualified, or until such director’s earlier removal, resignation, death or disability, in each case, in accordance with the DGCL, the Certificate of Incorporation and the Bylaws.

7. Officers. Each officer of HCM II as of immediately prior to the Effective Time shall be an officer of the Corporation from and after the Effective Time, and shall retain the same title with the Corporation from and after the Effective Time as he or she had with HCM II immediately prior to the Effective Time, each of whom shall serve until such time as their respective successors have been designated by the board of directors, or until such officer’s earlier removal, resignation, death or disability, in each case, in accordance with the DGCL, the Certificate of Incorporation and the Bylaws.

8. Effects of Domestication. Immediately upon the Effective Time, the Domestication shall have the effects set forth in Section 265(f) of the DGCL, including, without limitation, all of the rights, privileges and powers of HCM II, and all property, real, personal and mixed, and all debts due to HCM II, as well as all other things and causes of action belonging to HCM II, will remain vested in the Corporation and will be the property of the Corporation and the title to any real property vested by deed or otherwise in HCM II will not revert or be in any way impaired by reason of the DGCL. Following the Domestication, all rights of creditors and all liens upon any property of HCM II will be preserved unimpaired, and all debts, liabilities and duties of HCM II will remain attached to the Corporation, and may be enforced against the Corporation to the same extent as if said debts, liabilities and duties had originally been incurred or contracted by the Corporation. The rights, privileges, powers and interests in property of HCM II as well as the debts, liabilities and duties of HCM II, will not be deemed, as a consequence of the Domestication, to have been transferred to the Corporation for any purpose of the laws of the State of Delaware.

9. Further Assurances. If at any time the Corporation, or its successors or assigns, shall consider or be advised that any further assignments or assurances in law or any other acts are necessary or desirable to carry out the purposes of this Plan of Domestication, HCM II and its directors and authorized officers shall be deemed to have granted to the Corporation an irrevocable power of attorney to execute and deliver all such proper deeds, assignments and assurances in law and to do all acts necessary or proper to vest, perfect or confirm title to and possession of such rights, properties or assets in the Corporation and otherwise to carry out the purposes of this Plan of Domestication, and the directors and authorized officers of the Corporation are fully authorized in the name of HCM II or otherwise to take any and all such action.

10. Amendment or Termination. This Plan of Domestication may be amended or terminated at any time before the Effective Time by action of the Board.

11. Miscellaneous. The provisions of this Plan of Domestication shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. This Plan of Domestication shall be governed by and construed in accordance with the laws of the State of Delaware, including the DGCL, without giving effect to any choice of law or conflict of law provisions or rule (except to the extent that the laws of the Cayman Islands govern the Domestication) that would cause the application of the laws of any jurisdiction other than the State of Delaware. This Plan of Domestication may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

***

IN WITNESS WHEREOF, this Plan of Domestication has been duly executed and delivered by a duly authorized officer of HCM II as of the date first written above.

STOCKHOLDERS MEETINGS

1.  Time and Place of Meetings. All meetings of stockholders will be held at such time and place, within or without the State of Delaware, as may be designated by the Board of Directors (the “Board”) of HCM II Acquisition Corp., a Delaware corporation (the “Corporation”), from time to time in such manner as set forth in the Corporation’s Certificate of Incorporation (the “Certificate of Incorporation”). Notwithstanding the foregoing, the Board may, in its sole discretion, determine that a meeting of stockholders will not be held at any place, but may instead be held by means of remote communications in a manner consistent with the General Corporation Law of the State of Delaware, as amended (the “DGCL”), subject to such guidelines and procedures as the Board may adopt from time to time. The Board may cancel or reschedule to an earlier or later date any previously scheduled annual or special meeting of stockholders.

2.  Annual Meetings. At each annual meeting of stockholders, the stockholders will elect the directors from the nominees for director, to succeed those directors whose terms expire at such meeting and will transact such other business, in such case as may properly be brought before the meeting in accordance with Sections 9, 10, 11 and 12. The Board may postpone, reschedule or cancel any previously scheduled annual meeting of stockholders, before or after the notice for such meeting has been sent to the stockholders.

3.  Special Meetings.(a) A special meeting of stockholders may be called only by such persons and only in such manner as set forth in the Certificate of Incorporation, in each case to transact only such business as is specified in the notice of such meeting.

4.  Notice of Meetings. Notice of every meeting of stockholders, stating the place, if any, date and time thereof, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, will be given, in a form permitted by Section 28 or by the DGCL, not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder of record entitled to vote at such meeting, except as otherwise provided by law. When a meeting is recessed or adjourned to another place, date, or time, notice need not be given of the recessed or adjourned meeting if the place, if any, date and time thereof, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such recessed or adjourned meeting, are (a) announced at the meeting at which the recess or adjournment is taken (b) displayed, during the time scheduled for the meeting, on the same electronic network used to enable stockholders and proxy holders to participate in the meeting by means of remote communication or (c) set forth in the notice of meeting; provided, however, that if the recess or adjournment is for more than thirty (30) days, or if after the recess or adjournment a new record date is fixed for the recessed or adjourned meeting, written notice of the place, if any, date and time thereof, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such recessed or adjourned meeting, must be given in conformity herewith.

5.  Inspectors. The Board will, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The Board may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the presiding officer of the meeting will appoint one or more inspectors to act at the meeting. The inspector shall have the duties prescribed by law and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law. Every vote taken by ballots shall be counted by a duly appointed inspector or duly appointed inspectors.

1

6.  Quorum. Except as otherwise provided by law, the Certificate of Incorporation, these bylaws (“Bylaws”), or in a certificate of designation of a series of preferred stock filed by the Board pursuant to the DGCL (“Preferred Stock Designation”), the holders of a majority in voting power of the shares of the capital stock of the Corporation issued and outstanding and entitled to vote at the meeting, present in person, present by means of remote communication in a manner, if any, authorized by the Board in its sole discretion, or represented by proxy, will constitute a quorum at a meeting of stockholders for the transaction of business thereat; provided, however, that where a separate vote by a class or classes or series of capital stock is required by law, the Certificate of Incorporation, these Bylaws, or in a Preferred Stock Designation, the holders of a majority in voting power of the shares of such class or classes or series of the capital stock of the Corporation issued and outstanding and entitled to vote on such matter, present in person, present by means of remote communication in a manner, if any, authorized by the Board in its sole discretion, or represented by proxy, shall constitute a quorum entitled to take action with respect to the vote on such matter. A quorum, once established, will not be broken by the subsequent withdrawal of enough votes to leave less than a quorum. If, however, such a quorum shall not be present or represented at any meeting of the stockholders, the presiding officer of the meeting shall have the power to recess or adjourn the meeting from time to time, in the manner provided in Section 14, until a quorum is present or represented. At any such adjourned meeting at which there is a quorum, any business may be transacted that might have been transacted at the meeting originally called.

7.  Voting List. The Corporation shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of stockholders entitled to vote at the meeting (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth (10th) day before the meeting date), arranged in alphabetical order and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting, (a) on a reasonably accessible electronic network as permitted by applicable law (provided that the information required to gain access to the list is provided with the notice of the meeting), or (b) during ordinary business hours, at the principal place of business of the Corporation. If the meeting is held at a location where stockholders may attend in person, a list of stockholders entitled to vote at the meeting shall also be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present at the meeting. If the meeting is held solely by means of remote communication, then the list shall be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access the list shall be provided with the notice of the meeting. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 7 or to vote in person or by proxy at any meeting of stockholders. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list.

8.  Voting; Proxies.

(a)  General. Except as otherwise provided by law, by the Certificate of Incorporation, in these Bylaws, or in a Preferred Stock Designation, each stockholder will be entitled at every meeting of the stockholders to one (1) vote for each share of stock having voting power standing in the name of such stockholder on the books of the Corporation on the record date for the meeting and such votes may be cast either in person or by proxy. Every proxy must be authorized in a manner permitted by Section 212 of the DGCL (or any successor provision) and may be documented, signed and delivered in accordance with Section 116 of the DGCL (or any successor provision) provided that such authorization shall set forth, or be delivered with, information enabling the Corporation to reasonably determine the identity of the stockholder granting such authorization.

2

(b)  Vote Required for Stockholder Action. When a quorum is present at any meeting of stockholders, the affirmative vote of a majority of the votes properly cast on the matter (excluding any abstentions or broker non-votes) will be the act of the stockholders with respect to all matters other than the election of directors (who will be elected by a plurality of all votes properly cast), except as otherwise provided in these Bylaws, the Certificate of Incorporation, a Preferred Stock Designation, the rules or regulations of any stock exchange applicable to the Corporation, or by law.

9.  Order of Business. Meetings of stockholders shall be presided over by the Chairperson, if any, or in his or her absence, by the Vice Chairperson, if any, or in his or her absence, by the Chief Executive Officer, or in his or her absence, by the President, or in his or her absence, by a Vice President, or in the absence of the foregoing persons by a chairperson designated by the Board, or in the absence of such designation, by a chairperson chosen at the meeting. The Secretary shall act as secretary of the meeting, but in his or her absence, the chairperson of the meeting may appoint any person to act as secretary of the meeting. Unless otherwise determined by the Board prior to the meeting, the presiding person of any meeting of stockholders will also determine the order of business and have the authority in his or her sole discretion to determine the rules of procedure and regulate the conduct of the meeting, including without limitation by: (a) imposing restrictions on the persons (other than stockholders of the Corporation or their duly appointed proxy holders) that may attend the meeting; (b) ascertaining whether any stockholder or his or her proxy holder may be excluded from the meeting based upon any determination by the presiding officer, in his or her sole discretion, that any such person has disrupted or is likely to disrupt the proceedings thereat; (c) determining the circumstances in which any person may make a statement or ask questions at the meeting; (d) ruling on all procedural questions that may arise during or in connection with the meeting; (e) determining whether any nomination or business proposed to be brought before the meeting has been properly brought before the meeting; and (f) determining the time or times at which the polls for voting at the meeting will be opened and closed.

In addition to the right to indemnification conferred in Section 27(a), an indemnitee shall also have the right to be paid by the Corporation, to the fullest extent not prohibited by applicable law, the expenses (including attorney’s fees) incurred by indemnitee in appearing at, participating in or defending any such proceeding in advance of its final disposition or in connection with a proceeding brought to establish or enforce a right to indemnification or advancement of expenses under this Section 27 (which shall be governed by Section 27(c) (hereinafter an “advancement of expenses”)); provided, however, that, if the DGCL requires or in the case of an advancement of expenses made in a proceeding brought to establish or enforce a right to indemnification or advancement of expenses, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer of the Corporation (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made solely upon delivery to the Corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified under Section 27(a) and Section 27(b) or otherwise.

(c)  Right of Indemnitee to Bring Suit.

(d)  Indemnification Not Exclusive. The provision of indemnification to or the advancement of expenses and costs to any indemnitee under this Section 27, or the entitlement of any indemnitee to indemnification or advancement of expenses and costs under this Section 27, shall not limit or restrict in any way the power of the Corporation to indemnify or advance expenses and costs to such indemnitee in any other way permitted by law or be deemed exclusive of, or invalidate, any right to which any indemnitee seeking indemnification or advancement of expenses and costs may be entitled under any law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such indemnitee’s capacity as an officer, director, employee or agent of the Corporation and as to action in any other capacity.

12

(e)  Corporate Obligations; Reliance. The rights granted pursuant to the provisions of this Section 27 shall vest at the time a person becomes a director or officer of the Corporation and shall be deemed to create a binding contractual obligation on the part of the Corporation to the persons who from time to time are elected as officers or directors of the Corporation, and such persons in acting in their capacities as officers or directors of the Corporation or any subsidiary shall be entitled to rely on such provisions of this Section 27 without giving notice thereof to the Corporation. Such rights shall continue as to an indemnitee who has ceased to be a director or officer and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, alteration or repeal of this Section 27 that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

(f)  Insurance. The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

The Corporation may, to the extent authorized from time to time by the Board, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation and to any person (in addition to an indemnitee) serving at the request of the Corporation as an officer, director, employee or agent of any other enterprise to the fullest extent of the provisions of this Section 27 with respect to the indemnification and advancement of expenses of indemnitees hereunder.

The term “Warrant Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which the shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) business days (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law), provided, that the Company shall provide at least three (3) days’ prior written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

Each outstanding Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.
--- ---
3.3 Exercise of Warrants.
3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, including without limitation, subsection 3.3.5, a Warrant may be exercised by the Registered Holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised (the “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election to Purchase”) shares of Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant Certificate, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) payment in full of the Warrant Price for each share of Common Stock as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, as follows:
--- ---
(a) in lawful money of the United States, in good bank draft or good certified check payable to the order of the Warrant Agent or by wire transfer of immediately available funds;
--- ---
4
(b) in the event of a redemption pursuant to Section 6 hereof in which the Company’s board of directors (the “Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this subsection 3.3.1(b), over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b) and Section 6.3, the “Fair Market Value” shall mean the average reported closing price of the shares of Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants, pursuant to Section 6 hereof; or
(c) on a cashless basis as provided in Section 7.4 hereof.
--- ---
3.3.2 Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares of Common Stock as to which such Warrant shall not have been exercised. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the Depositary, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act of 1933, as amended (the “Securities Act”)  with respect to the shares of Common Stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4 or a valid exemption from registration is available. No Warrant shall be exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the Common Stock issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant. In no event will the Company be required to net cash settle the Warrant exercise. The Company may require holders of Public Warrants to settle the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless basis,” the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.
--- ---
3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and non- assessable.
--- ---
3.3.4 Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.
--- ---
5
3.3.5 Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates) or any “group” of which the holder or its affiliate is a member, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify)(the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates, or any group of which such person and its affiliates is a member, shall include the number of shares of Common Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates, or any group of which any such person or its affiliates is a member, and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates, or any group of which such person or its affiliates is a member (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the applicable regulations of the Commission. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Commission, and the percentage held by the holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. To the extent that a holder makes the election described in this subsection 3.3.5, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant unless it provides to the Warrant Agent in its Election to Purchase, a certification that, upon after giving effect to such exercise, such person (together with such person’s affiliates) or any “group” of which such holder or its affiliates is a member, would not beneficially own in excess of the Maximum Percentage of the Common Stock outstanding immediately after giving effect to such exercise as determined in accordance with this subsection 3.3.5. For purposes of the Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the U.S. Securities and Exchange Commission (the “Commission”)  as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) business days, confirm orally and in writing to such holder the number of shares of Common<br>Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.
4. Adjustments.
--- ---
4.1 Stock Dividends.
--- ---
4.1.1 Split-Ups. If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price less than the “Fair Market Value” (as defined below) shall be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for the Common Stock) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering and divided by (y) the Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights..
--- ---

4.1.2 Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to all or substantially all of the holders of shares of Common Stock on account of such shares of Common Stock (or other shares of the Company’s  capital stock into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, or (b) Ordinary Cash Dividends (as defined below) (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50. Solely for purposes of illustration, if the Company, at a time while the Warrants are outstanding and unexpired, pays a cash dividend of $0.35 and previously paid an aggregate of $0.40 of cash dividends and cash distributions on the Common Stock during the 365-day period ending on the date of declaration of such $0.35 dividend, then the Warrant Price will be decreased, effectively immediately after the effective date of such $0.35 dividend, by $0.25 (the absolute value of the difference between $0.75 (the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period, including such $0.35 dividend) and $0.50 (the greater of (x) $0.50 and (y) the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period prior to such $0.35 dividend)).
4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

4.3 Adjustments in Warrant Price.
--- ---
4.3.1 Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

4.3.2 [RESERVED]

4.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by subsections 4.1.1, 4.1.2 or Section 4.2 hereof or that solely affects the par value of such Common Stock), or in the case of any merger or consolidation of the Company with or into another entity or conversion of the Company as another entity (other than a consolidation or merger in which the Company is the continuing corporation and is not a subsidiary of another entity whose stockholders did not own all or substantially all of the Common Stock of the Company in substantially the same proportions immediately before such transaction and that does not result in any reclassification or reorganization of the outstanding Common Stock), or in the case of any sale or conveyance to another entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however, that (i) if the holders of the shares of Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the shares of Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of the shares of Common Stock under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 65% of the voting power of the Company’s outstanding equity securities (including with respect to the election of directors), the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the weighted average of the amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and participated in such tender or exchange offer on a pro rata basis with all other holders of Common Stock, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided further that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in the form of capital stock or shares in the successor entity that is listed for trading on a national securities exchange<br>or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference (but in no event less than zero) of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes model as calculated by an accounting, appraisal, investment banking firm or consultant of nationally recognized standing that is, in the good faith judgment of the Board, qualified to make such calculation. “Per Share Consideration” means (i) if the consideration paid to holders of the Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock, and (ii) in all other cases, the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event will the Warrant Price be reduced to less than the par value per share issuable upon exercise of the Warrant.
4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.
8
4.6 No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder.
4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.
--- ---
4.8 Other Events. In case any event shall occur affecting the Company as to which none of the provisions of the preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary, the terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. For the avoidance of doubt, all adjustments made pursuant to this Section 4.8 shall be made equally to all outstanding Warrants.

4.9 [RESERVED]

5. Transfer and Exchange of Warrants.
5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, in the case of a certificated Warrant, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.
--- ---
9
5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or in any Book- Entry Warrant Certificate or Definitive Warrant Certificate, each Book-Entry Warrant Certificate and Definitive Warrant Certificate may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.
5.3 Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.
--- ---
5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.
--- ---
5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

6. Redemption.
6.1 Redemption of Warrants for Cash. All, but not less than all, of the outstanding Warrants may be redeemed (in whole and not in part), at the option of the Company, at any time during the Exercise Period, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.2 below, at a Redemption Price (as defined below) of $0.01 per Warrant; provided that (a) the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the Measurement Period and the 30-day Redemption Period (each as defined in Section 6.2 below).
--- ---
6.2 Date Fixed for, and Notice of, Redemption; Redemption Price; Reference Value. In the event that the Company elects to redeem the Warrants pursuant to Section 6.1, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (such period, the “Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice.
--- ---
6.3 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with Section 3 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date. In the event the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1(b), the notice of redemption will contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

7. Other Provisions Relating to Rights of Holders of Warrants.
7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.
--- ---
7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.
--- ---
7.3 Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.
--- ---
7.4 Registration of Common Stock; Cashless Exercise at Company’s Option.
--- ---
7.4.1 Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than twenty (20) business<br>days after the Effective Date, it shall use its commercially reasonable efforts to file with the Commission a post-effective amendment<br>to the Registration Statement, or a new registration statement registering, under the Securities Act, the issuance of the shares of Common<br>Stock issuable upon exercise of the Warrants. The Company shall use its commercially reasonable efforts to cause the same to become effective<br>and to maintain the effectiveness of such post-effective amendment or registration statement, and a current prospectus relating thereto,<br>until the expiration or redemption of the Warrants in accordance with the provisions of this Agreement. If any such post-effective or<br>registration statement has not been declared effective by the sixtieth (60th) business day following the Effective Date, holders of the<br>Warrants shall have the right, during the period beginning on the sixty-first (61st) business day after the Effective Date and ending<br>upon such post-effective amendment or registration statement being declared effective by the Commission, and during any other period when<br>the Company shall fail to have maintained an effective registration statement covering the shares of Common Stock issuable upon exercise<br>of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9)<br>of the Securities Act (or any successor rule) or another exemption) for that number of shares of Common Stock equal to the quotient obtained<br>by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the excess of the “Fair<br>Market Value” (as defined below) over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1,<br>“Fair Market Value” shall mean the average reported closing price of the shares of Common Stock as reported during the ten<br>(10) trading day period ending on the third (3rd) trading day prior to the date that notice of exercise is received by the Warrant Agent<br>from the holder of such Warrants or its securities broker or intermediary. The date that notice of “cashless exercise” is<br>received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise”<br>of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall<br>be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a “cashless basis”<br>in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares of Common Stock<br>issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such<br>term is defined in Rule 144 under the Securities Act (or any successor rule)) of the Company and, accordingly, shall not be required to<br>bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants<br>have been exercised or have expired, the Company shall continue to be obligated to comply with its registration obligations under the<br>first three sentences of this subsection 7.4.1.
--- ---
7.4.2 Cashless Exercise at Company’s Option. If the shares of Common Stock are at the time of any exercise of a Warrant not listed on a national securities exchange such that they satisfy the definition of “covered securities” under Section 18(b)(1) of the Securities Act (or any successor rule), the Company may, at its option, require holders of Public Warrants who exercise their Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) as described in subsection 7.4.1 and (i) in the event the Company so elects, the Company shall not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the shares of Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary or (ii) if the Company does not so file or maintain such registration statement, the Company agrees to use its commercially reasonable efforts to register or qualify for sale the Common Stock issuable upon exercise of the Public Warrants under the applicable blue sky laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available.

8. Concerning the Warrant Agent and Other Matters.
8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock.

--- ---
8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

--- ---
8.3.2 Further Assurances.

8.4 Liability of Warrant Agent.
8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Vice President, Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.
--- ---
8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, out of pocket costs and reasonable outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith.
8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock shall, when issued, be valid and fully paid and non-assessable.
--- ---
8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of the Warrants.

9.3 Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be the exclusive forum for any such action, proceeding or claim. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. Any person or entity purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented to the forum provisions in this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of New York or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

9.4 Persons Having Rights under this Agreement.

All covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the Registered Holders of the Warrants.

A copy of this Agreement shall be available at all reasonable times at the office of the Warrant Agent in the Borough of Manhattan, City and State of New York, for inspection by the Registered Holder of any Warrant.

Warrant Certificate


This Warrant Certificate certifies that [●] (the “Holder”), or registered assigns, is the registered holder of warrant(s) evidenced hereby (the **“Warrants”**and each, a “Warrant”) to purchase shares of common stock, $0.0001 par value per share (the “Common Stock”), of Terrestrial Energy Inc., a Delaware corporation (the “Company”). Each whole Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Warrant Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Each whole Warrant is initially exercisable for one fully paid and non-assessable share of Common Stock. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

The initial Warrant Price per share of Common Stock for any Warrant is equal to $11.50 per share. The Warrant Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement. In addition, and notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, to the extent that the holder of a Warrant has delivered a notice contemplated by subsection 3.5.5 of the Warrant Agreement, neither the Company nor the Warrant Agent shall issue to Holder, and Holder may not acquire, any right it might have to acquire, a number of shares of Common Stock upon exercise of any Warrant to the extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by Holder would exceed the Maximum Percentage of Common Stock outstanding immediately after giving effect to such exercise as determined in accordance with subsection 3.3.5. of the Warrant Agreement.

Exhibit B-1

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.

This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York.

2.1.3 New Registrable Securities. Subject to Section<br>3.4, in the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis,<br>the Company shall, upon the written request of such Holder, promptly use its commercially reasonable efforts to cause the resale of such<br>Registrable Securities to be covered by either, at the Company’s option, any then-available Shelf (including by means of a post-effective<br>amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such<br>Shelf or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, that the Company shall only be<br>required to cause such Registrable Securities to be so covered twice per calendar year for the Sponsor Holders, collectively.

All requests<br>for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of<br>Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Company shall have<br>the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment<br>banks), subject to the initial Demanding Holder’s prior approval (which approval shall not be unreasonably withheld, conditioned<br>or delayed). Subject to Section 2.4.6, the Sponsor Holders, collectively, may demand Underwritten Shelf Takedowns pursuant to<br>this Section 2.1.4 not more than two (2) times in any 12-month period (the “Yearly Limit”).

To facilitate the allocation of Registrable Securities<br>in accordance with the above provisions, the Company or the Underwriters may round the number of shares allocated to any Holder to the<br>nearest ten (10) Registrable Securities.

Following the receipt of any Withdrawal Notice, the Company shall<br>promptly forward such Withdrawal Notice to any other Requesting Holders.

Subject to Section 2.2.2, the Company shall, in good faith, cause such Registrable Securities to<br>be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter<br>or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Holders pursuant to this Section<br>2.2.1 to be included therein on the same terms and conditions as any similar securities of the Company included in such registered<br>offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution<br>thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder’s<br>agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by<br>the Company.

The terms of such lock-up agreements<br>shall be negotiated among the applicable Holders, the Company and the Underwriters and shall include customary exclusions from the restrictions<br>on Transfer set forth therein. The Company will not be obligated to undertake an Underwritten Shelf Takedown during any Underwritten<br>Lock-Up Period binding on the Holders, nor will the Company be obligated to include in any Piggyback Registration any Registrable Securities<br>that are then subject to a “lock-up” agreement.

Subject to receipt from the Holder by the Company and the Transfer Agent of customary representations<br>and other documentation reasonably acceptable to the Company and the Transfer Agent in connection therewith, the Holder may request that<br>the Company remove any legend from the book entry position evidencing its Registrable Securities and the Company will, if required by<br>the Transfer Agent, use its commercially reasonable efforts to cause its legal counsel to deliver a legal opinion, in a form reasonably<br>acceptable to the Transfer Agent, to the effect that the removal of such restrictive legends in such circumstances may be effected under<br>the Securities Act, following the earliest of such time as such Registrable Securities (i) are subject to or have been or are about to<br>be sold pursuant to an effective registration statement or (ii) have been or are about to be sold pursuant to Rule 144 promulgated under<br>the Securities Act (or any successor rule promulgated thereafter by the Commission). If restrictive legends are no longer required for<br>such Registrable Securities pursuant to the foregoing, the Company shall, in accordance with the provisions of this Section 2.5<br>promptly after any request therefor from the Holder accompanied by such customary and reasonably acceptable representations and other<br>documentation referred to above establishing that restrictive legends are no longer required, deliver to the Transfer Agent irrevocable<br>instructions that the Transfer Agent shall make a new, unlegended entry for such book entry shares.

--- ---
3.4.2 If the filing, initial effectiveness or continued use of<br>a Registration Statement in respect of any Registration at any time would (i) require the Company to make an Adverse Disclosure, (ii)<br>require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the<br>Company’s control or (iii) in the good faith judgment of the majority of the Board, be seriously detrimental to the Company, and<br>the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at<br>such time, the Company may, upon giving prompt written notice of such action to the Holders (which notice shall not specify the nature<br>of the event giving rise to such delay or suspension), delay the filing or initial effectiveness of, or suspend use of, such Registration<br>Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the<br>Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice<br>referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable<br>Securities until such Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed,<br>and in each case maintain the confidentiality of such notice and its contents.

3.4.3 Subject to Section 3.4.4, if (i) during the period<br>starting with the date 60 days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date 120<br>days after the effective date of, a Company-initiated Registration, and provided that the Company continues to actively employ,<br>in good faith, all commercially reasonable efforts to maintain the effectiveness of the applicable Shelf Registration, or (ii) if, pursuant<br>to Section 2.1.4, Holders have requested an Underwritten Shelf Takedown and the Company and such Holders are unable to obtain<br>the commitment of underwriters to firmly underwrite such offering, then, in each case, the Company may, upon giving prompt written notice<br>of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4.
3.4.4 The right to delay or suspend any filing, initial effectiveness<br>or continued use of a Registration Statement pursuant to Section 3.4.2 or a registered offering pursuant to Section 3.4.3<br>shall be exercised by the Company, in the aggregate, for not more than 90 consecutive calendar days or more 120 total calendar days in<br>each case, during any 12-month period.
--- ---
3.5 Reporting Obligations. As long as any Holder shall<br>own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to use<br>commercially reasonable efforts to file timely (or obtain extensions in respect thereof and file within the applicable grace period)<br>all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act.

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.
4.1.1 The Company agrees to indemnify, to the extent permitted by<br>law, each Holder of Registrable Securities, its officers, directors and agents and each Person who controls such Holder (within the meaning<br>of the Securities Act) against all losses, claims, damages, liabilities and reasonable and documented out-of-pocket expenses (including,<br>without limitation, reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact<br>contained in or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof<br>or supplement thereto filed pursuant to this Agreement or any omission or alleged omission of a material fact required to be stated therein<br>or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information<br>or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters,<br>their officers and directors and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent<br>as provided in the foregoing with respect to the indemnification of the Holder.
--- ---
4.1.2 In connection with any Registration Statement filed pursuant<br>to this Agreement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or cause to be furnished)<br>to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration<br>Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the<br>Company, its directors, officers and agents and each Person who controls the Company (within the meaning of the Securities Act) against<br>all losses, claims, damages, liabilities and reasonable and documented out-of-pocket expenses (including, without limitation, reasonable<br>outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in or incorporated by<br>reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission<br>or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but<br>only to the extent that such untrue statement is contained in (or not contained in, in the case of an omission) any information or affidavit<br>so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be<br>several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities<br>shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to<br>such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each<br>person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing<br>with respect to indemnification of the Company.
--- ---
15
4.1.3 Any Person entitled to indemnification herein shall (i) give<br>prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the<br>failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not<br>materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest<br>between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the<br>defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party<br>shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not<br>be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be<br>obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to<br>such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party<br>and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified<br>party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money<br>(and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement<br>or admission of fault and culpability on the part of such indemnified party or which settlement does not include as an unconditional<br>term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim<br>or litigation.
4.1.4 The indemnification provided for under this Agreement shall<br>remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director<br>or controlling Person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable<br>Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for<br>contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.
--- ---
4.1.5 If the indemnification provided under Section 4.1<br>hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims,<br>damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified<br>party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities<br>and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified<br>party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall<br>be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of<br>a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or<br>relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and<br>the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct<br>or prevent such action; provided, however, that the liability of any Holder under this Section 4.1.5 shall be limited to<br>the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by<br>a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth<br>in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably<br>incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable<br>if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation,<br>which does not take account of the equitable considerations referred to in this Section 4.1.5. No Person guilty of fraudulent<br>misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section<br>4.1.5 from any Person who was not guilty of such fraudulent misrepresentation.

4.2 Waiver of Medallion Guaranty. The Company agrees to<br>use commercially reasonable efforts to enter into that certain indemnification agreement, substantially in the form attached as Exhibit<br>B to this Agreement, in favor of Continental Stock Transfer & Trust Company (or any successor transfer agent or warrant agent<br>of the Company) in connection with the waiver of any requirement to provide a medallion guarantee in connection with any Transfer of<br>any equity securities of the Company by any Sponsor Holder or Cantor or any of their respective Permitted Transferees; provided<br>that, in each case, as a prerequisite to the Company’s entry into such indemnification agreement, such Sponsor Holder or Cantor<br>or their respective Permitted Transferee enters into an indemnification agreement, substantially in the form attached as Exhibit C<br>to this Agreement, in favor of the Company.

--- ---

provided, however, that (A) in the case of clauses (ii) through (xii), as a prerequisite to such Transfer, such permitted transferee(s) must enter into joinder to this Agreement, substantially in the form of Exhibit A hereto, in order to become a “Securityholder” for purposes of this Agreement.

4. Prohibited Transfers. In furtherance of the foregoing,<br>SPAC, and any duly appointed transfer agent for the registration or transfer of the securities described therein, are hereby authorized<br>to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Agreement.
--- ---
5. Amendment.

(b) Annual Increase in Shares. On the first day of each January during the term of the Plan, commencing on January 1, 2026 and ending on (and including) January 1, 2035, the aggregate number of Shares that may be issued under the Plan shall automatically increase by a number equal to the lesser of (i) five percent (5%) of the total number of Shares actually issued and outstanding on the last day of the preceding Fiscal Year or (ii) a number of Shares determined by the Board.

(c) Shares Returning toShare Reserve. Any Shares subject to an Award that expires or is canceled, forfeited, or terminated without issuance of the full number of Shares to which the Award related will again be available for issuance under the Plan. Notwithstanding anything to the contrary contained herein, Shares subject to an Award under the Plan shall not again be made available for issuance or delivery under the Plan if such shares are (a) shares tendered in payment of an Option, (b) shares delivered or withheld by the Company to satisfy any tax withholding obligation, or (c) shares covered by a stock-settled Stock Appreciation Right or other Awards that were not issued upon the settlement of the Award. To the extent permitted under applicable exchange listing requirements, any dividend equivalents paid or credited under the Plan with respect to Restricted Stock Units shall not be applied against the number of Shares that may be issued under the Plan, whether or not such dividend equivalents are converted into Restricted Stock Units. The maximum number of Shares may be increased from time to time by approval of the Board and by the stockholders of the Company if, in the opinion of counsel for the Company, stockholder approval is required. During the terms of the Awards, the Company shall keep available at all times the number of Shares reasonably required to satisfy such Awards, which Shares may consist, in whole or in part, of authorized and unissued shares, treasury shares or shares reacquired by the Company in any manner.

8

(d) Awards Not Reducing Share Reserve. Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the Share Reserve; provided, that, Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as Incentive Stock Options shall be counted against the ISO Limit. Subject to applicable stock exchange requirements and applicable law, available shares under a shareholder-approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect such acquisition or transaction) may be used for Awards under the Plan and shall not count toward the Share Reserve. The Shares may be either authorized and unissued Shares or previously issued Shares acquired by the Company on the open market or otherwise.

(e) Non-Employee Director Limit. The maximum number of Shares subject to Awards granted during a single Fiscal Year to any Eligible Non-Employee Director, together with any cash fees paid to such Eligible Non-Employee Director during the Fiscal Year shall not exceed a total value of $400,000 (calculating the value of any Awards based on the grant date fair value for financial reporting purposes); provided however that (i) the Committee may make exceptions to this limit, except that the Non-Employee Director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous decisions involving compensation for Non-Employee Director and (ii) the limitation that will apply in the fiscal year in which the Eligible Non-Employee Director (A) is initially appointed or elected to the Board, (B) serves on a special committee of the Board, or (iii) serves as lead director or non-executive chair of the Board, shall be $800,000.

4.4 Other Distributionsand Changes in the Stock. In the event that:

(a) the Company shall at any time distribute with respect to the Stock assets or securities of persons other than the Company (excluding (i) cash or (ii) distributions referred to in Section 4.3), or

(b) the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company, or

(c) there shall be any other change (except as described in Section 4.3) in the number or kind of outstanding Shares or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged,

the Committee may, in its sole discretion, determine that such event equitably requires an adjustment in the number or kind of Shares subject to an Option or other Award, an adjustment in the Option Price or the taking of any other action by the Committee, including, without limitation, the setting aside of any property for delivery to the Participant upon the exercise of an Option or the full vesting of an Award. If the Committee makes such a determination, then such adjustments shall be made, or other action shall be taken, by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option or Award that involves the particular type of stock for which a change was effected.

4.5 General AdjustmentRules. No adjustment or substitution provided for in this Article IV shall require the Company to sell a fractional Share under any Option, or otherwise issue a fractional Share, and the total substitution or adjustment with respect to each Option and other Award shall be limited by deleting any fractional Share. In the case of any such substitution or adjustment, the aggregate Option Price for the total number of Shares then subject to an Option shall remain unchanged but the Option Price per Share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of Shares or other securities into which the Stock subject to the Option may have been changed and appropriate adjustments shall be made to other Awards to reflect any such substitution or adjustment.

4.6 Determination by theCommittee, Etc*.* Adjustments under this Article IV shall be made by the Committee, whose determinations with regard thereto shall be made in a manner that complies with Sections 409A and 424 of the Code, as applicable, and shall be final and binding upon all parties thereto.

Article V

CHANGE IN CONTROL

5.1 Change in ControlProvisions. The following provisions shall apply to Awards in the event of a Change in Control unless otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the holder of the Award or unless otherwise expressly provided by the Committee at the time of grant of the Award. Except as otherwise stated in the Award Agreement, in the event of a Change in Control, then, notwithstanding anything to the contrary set forth herein, the Committee may unilaterally take one or more of the following actions with respect to the Awards, without Participant consent, contingent upon the closing or completion of the Change in Control:

(a) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Award or to substitute a similar stock award for the Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Change in Control);

10

(b) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Stock issued pursuant to the Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company);

(c) accelerate the vesting, in whole or in part, of the Award (and, if applicable, the time at which the Award may be exercised) to a date prior to the closing of such Change in Control as the Committee shall determine (or, if the Committee shall not determine such a date, to the date that is five days prior to the closing of the Change in Control), with such Award terminating if not exercised (if applicable) at or prior to the closing of the Change in Control;

(d) arrange for the lapse of any reacquisition or repurchase rights held by the Company with respect to the Award;

(e) cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the closing of the Change in Control, in exchange for such cash consideration, if any, as the Committee, in its sole discretion, may consider appropriate; and

(f)   make a payment, in such form as may be determined by the Committee, equal to the excess, if any, of (i) the value of the property the holder of the Award would have received upon the exercise of the Award, over (ii) any exercise price payable by such holder in connection with such exercise. For the avoidance of doubt, such payment may be zero if the fair market value of the property is equal to or less than the exercise price.

The Committee need not take the same action with respect to all Awards or with respect to all Participants. To the extent permitted under Section 409A of the Code, the Committee may provide that payments under this provision may be delayed to the same extent that payment of consideration to the holders of Stock in connection with the Change in Control is delayed as the result of escrows, earnouts, holdbacks or other contingencies. In addition, the Committee may provide that such payments made over time will remain subject to substantially the same vesting schedule as the Award, including any performance-based metrics that applied to the Award immediately prior to the closing or completion of the Change in Control.

5.2 Company Actions. The grant of Awards under the Plan shall in no way affect the right of the Company or any Affiliate to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part of its business or assets.

5.3 Dissolution orLiquidation. Except as otherwise provided in the applicable Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Awards (other than Awards consisting of vested and outstanding Shares not subject to a forfeiture condition or the Company’s right of repurchase) shall terminate immediately prior to the completion of such dissolution or liquidation, and the Shares subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Award is providing Service, provided, however, that the Committee may, in its sole discretion, cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

11

Article VI

PARTICIPATION

Participants may be granted from time to time one or more Awards; provided, however, that the grant of each such Award shall be separately approved by the Committee and receipt of one such Award shall not result in automatic receipt of any other Award.

Each Participant shall, if required by the Committee, enter into an Award Agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of the Plan, specifying such terms, conditions, rights and duties.

Article VII

7.1 Grant of Options. Coincident with or following designation for participation in the Plan, a Participant may be granted one or more Options. The Committee, in its sole discretion, shall designate whether an Option is an Incentive Stock Option or a Non-Qualified Stock Option; provided, however, that only Non-Qualified Stock Options may be granted to Eligible Consultants and Eligible Non-Employee Directors.

Incentive Stock Options and Non-Qualified Stock Options, whether granted at the same time or at different times, shall be deemed to have been awarded in separate grants and shall be clearly identified, and in no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of Shares for which any other Option may be exercised. In no event shall the Company have any obligation or liability to a Participant if an Option intended to qualify as an Incentive Stock Option is determined not to qualify as an Incentive Stock Option.

7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement (an “Option Agreement”). An Option Agreement shall be issued by the Company in the name of the Participant to whom the Option is granted and in such form as may be approved by the Committee.

(b) Price. The price at which each Share covered by an Option may be purchased (the “Option Price”) shall be determined in each case by the Committee and set forth in the Option Agreement.

(c) Duration of Options; Vesting. Each Option Agreement shall state the Option Period applicable to the Option, which must end, in all cases, not more than 10 years from the date the Option is granted (or five years, to the extent provided in Section 7.3).

(d) Vesting. The Option shall become exercisable, in whole or in part, at the same time or times as the Shares underlying the Option vest.

(e) Terminationof Service, Death, Disability, Etc. The Committee may specify the period, if any, during which an Option may be exercised following termination of the Optionholder’s Service. The effect of this subsection 7.2(e) shall be limited to determining the consequences of a termination of Service on an Option and nothing in this subsection 7.2(e) shall restrict or otherwise interfere with the Company’s discretion with respect to the termination of any individual’s Service. If the Committee does not otherwise specify, the following shall apply:

(i)   If the Service of the Optionholder is terminated within the Option Period for Cause, the Option shall thereafter be void for all purposes and immediately cancelled in its entirety for no consideration upon the date of the Optionholder’s termination of Service.

(ii) Unless otherwise provided in an Award Agreement, if the Optionholder becomes Disabled while still in Service of the Company or an Affiliate, the Option may be exercised by the Optionholder within one year following the Optionholder’s termination of Service on account of Disability (provided that such exercise must occur within the Option Period) and immediately thereafter, the Option will automatically terminate. In any such case, the Option may be exercised only as to the Shares that had become vested on or before the date of the Optionholder’s termination of Service because of Disability.

(iii)  Unless otherwise provided in an Award Agreement, if the Optionholder dies during the Option Period while still in Service of the Company or an Affiliate or within the one year period referred to in (ii) above or the three-month period referred to in (iv) below, the Option may be exercised by those entitled to do so under the Optionholder’s will or by the laws of descent and distribution within one year following the Optionholder’s death (provided that such exercise must occur within the Option Period), and immediately thereafter, the Option will automatically terminate. In any such case, the Option may be exercised only as to the Shares that had become vested on or before the date of the Optionholder’s death.

13

(iv) Unless otherwise provided in an Award Agreement, if the Service of the Optionholder is terminated within the Option Period for any reason other than Cause, Disability or death, the Option may be exercised by the Optionholder within three months following the date of the Optionholder’s termination of Service (provided that such exercise must occur within the Option Period), and immediately thereafter, the Option will automatically terminate. In any such case, the Option may be exercised only as to the Shares that had become vested on or before the date of termination of Service.

(f) NoService Right. Nothing in the Plan shall limit or impair the right of the Company or any Affiliate to terminate the employment of any employee or to terminate the consulting or advisory services of any consultant or advisor.

(g) Exercise, Payments, Etc.

(i) Mannerof Exercise. The method for exercising each Option granted hereunder shall be by delivery to the Company of written notice on any business day specifying the number of Shares with respect to which such Option is exercised. The Option shall be exercised when the Option Price for the number of Shares as to which the Option is exercised and applicable tax withholding is paid to the Company in full. If the Shares are certificated, a properly executed certificate or certificates representing the Shares shall be delivered to or at the direction of the Optionholder upon payment therefor.

(ii) The exercise price shall be paid by any of the following methods or any combination of the following methods at the election of the Optionholder, or by any other method approved by the Committee:

The aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by an Optionholder in any calendar year, under the Plan or otherwise, shall not exceed $100,000 (or such higher amount as may at the time of grant be applicable under Section 422(d) (or any successor provision) of the Code). For this purpose, the Fair Market Value of the Shares shall be determined as of the date of grant of the Option and Incentive Stock Options shall be taken into account in the order granted. The portion of any Incentive Stock Option accelerated in connection with a Change in Control shall remain exercisable as an Incentive Stock Option only to the extent the above limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such Incentive Stock Option shall thereafter be exercisable as a Non-Qualified Stock Option.

No right or interest of any Optionholder in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Optionholder, either voluntarily or involuntarily, or be subjected to any lien, directly or indirectly, by operation of law or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy, except as set forth above. In the event the Option is assigned or transferred in any manner contrary to terms of the Plan, then all Options transferred or assigned shall immediately terminate.

7.5 Stockholder Privileges. No Optionholder shall have any rights as a stockholder with respect to any Shares covered by an Option until the Optionholder becomes the holder of record of such Shares, and no adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date such Optionholder becomes the holder of record of such Shares.

WITHHOLDING

15.1 Withholding Requirement. The Company or any Affiliate, as the case may be, shall have the right to deduct from payments of any kind otherwise due to a Participant, or to condition the Company’s obligation to deliver Shares upon the exercise of any Option, the vesting of or lapse of Forfeiture Restrictions or repurchase rights with respect to any Restricted Stock Award or Restricted Stock Unit Award, to exercise Stock Appreciation Rights, or to grant Stock upon the payment by the Participant of, any federal, state, local or foreign taxes of any kind required by applicable law with respect to the grant or issuance of, or the vesting of or other lapse of restrictions applicable to, the applicable Award or the Shares subject to, or issuable upon exercise of, such Award. At the time of such grant, issuance, vesting or lapse, the Participant shall pay to the Company or Affiliate, as the case may be, any amount that the Company or Affiliate may reasonably determine to be necessary to satisfy such withholding obligation.

23

15.2  Withholding With Stock. At the time the Committee grants an Award or at any time thereafter, it may, in its sole discretion, grant the Participant an election to pay all such amounts of tax withholding, or any part thereof, by electing (a) to have the Company withhold from Shares otherwise issuable to the Participant, Shares having a value equal to the amount required to be withheld or such lesser amount as may be elected by the Participant; provided however, that the number of Shares so withheld shall not exceed the maximum amount required to be withheld (or such lesser amount as may be necessary to avoid classification as a liability under applicable accounting standards), or (b) to transfer to the Company a number of Shares that were acquired by the Participant more than six months prior to the transfer to the Company and that have a value equal to the amount required to be withheld or such lesser amount as may be elected by the Participant. All elections shall be subject to the approval or disapproval of the Committee. The value of Shares to be withheld shall be based on the Fair Market Value of the Stock on the date that the amount of tax to be withheld is to be determined (the “Tax Date”). Any such elections by Participants to have Shares withheld for this purpose will be subject to the following restrictions:

(a) All elections must be made prior to the Tax Date.

(b) All elections shall be irrevocable.

(c) If the Participant is an officer or director of the Company within the meaning of Section 16 of the Exchange Act (“Section 16”), the Participant must satisfy the requirements of Section 16 and any applicable rules thereunder with respect to the use of Stock to satisfy such tax withholding obligation.

Article XVI

REQUIREMENTS OF LAW

16.1 Requirements of Law. The issuance of Stock and the payment of cash pursuant to the Plan shall be subject to all applicable laws, rules and regulations.

16.2 Federal Securities Law Requirements. If a Participant is an officer or director of the Company within the meaning of Section 16, Awards granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule promulgated under the Exchange Act, to qualify the Award for any exception from the provisions of Section 16(b) of the Exchange Act available under that Rule. Such conditions shall be set forth in the agreement with the Participant which describes the Award or other document evidencing or accompanying the Award.

24

16.3  Section409A*.* Notwithstanding anything to the contrary set forth herein, the Plan and Awards made under the Plan will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards exempt from Section 409A of the Code, and to the extent not so exempt, in compliance with the requirements imposed by Section 409A of the Code. If any Plan provision or Award would result in the imposition of an additional tax under Section 409A of the Code, the Company and the Participant intend that the Plan provision or Award will be reformed to avoid imposition, to the extent possible, of the applicable tax and no action taken to comply with Section 409A of the Code shall be deemed to adversely affect the Participant’s rights to an Award. The Participant further agrees that the Committee, in the exercise of its sole discretion and without the consent of the Participant, may amend or modify an Award in any manner and delay the payment of any amounts payable pursuant to an Award to the minimum extent necessary to meet the requirements of Section 409A of the Code as the Committee deems appropriate or desirable. The Company makes no representation that the Plan or any Award complies with Section 409A of the Code and shall have no liability to any Participant for any failure to comply with Section 409A of the Code. A termination of employment or service shall not be deemed to have occurred for purposes of any provision of the Plan or any Award Agreement providing for the payment of any amount or benefit that constitutes a “nonqualified deferred compensation plan” upon or following a termination of employment or service, unless such termination is also a “separation from service” within the meaning of Section 409A of the Code, and, for purposes of any such provision of the Plan or any Award Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary set forth herein or in any Award Agreement, if the Participant is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or benefit in respect of an Award that is considered “nonqualified deferred compensation” under Section 409A of the Code payable on account of a “separation from service,” such payment or benefit shall not be made or provided until the date which is the earlier of (a) the expiration of the six-month period measured from the date of such “separation from service” of the Participant and (b) the date of the Participant’s death, solely to the extent required under Section 409A of the Code. Upon the expiration of the foregoing delay period, all payments and benefits in respect of such Award delayed pursuant to the foregoing (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Participant in a lump sum, and all remaining payments and benefits due in respect of such Award under the Plan or any Award Agreement, as applicable, shall be paid or provided in accordance with the normal payment dates specified for them herein.

16.4 Governing Law. The Plan and all agreements hereunder shall be construed in accordance with and governed by the laws of the State of Delaware excluding its conflict of laws rules.

Article XVII

For the avoidance of doubt, Employee’s past, present or future exercise of any rights described in this Section 3 shall not constitute a breach of this Agreement. In addition, 18 U.S.C. §1833(b) provides as follows, and nothing in this Agreement or any other agreement, or any Company policy, is intended to conflict with this statutory protection: “(1) Anindividual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secretthat (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to anattorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaintor other document filed in a lawsuit or other proceeding, if such filing is made under seal.

(b) Proceedings by or in the Right of the Company. Subject to Section 9 and Section 10 of this Agreement, the Company shall indemnify Indemnitee, to the fullest extent permitted by Delaware law in effect on the date hereof, or as such laws may from time to time hereafter be amended to increase the scope of such permitted indemnification, against any and all Expenses if Indemnitee was or is or becomes a party to or participant in, or is threatened to be made a party to or participant in, any Claim brought by or in the right of the Company by reason of or arising in part out of an Indemnifiable Event, including, without limitation, Claims in which the Indemnitee is solely a witness. In the event the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever (other than a determination pursuant to this Agreement that Indemnitee is not entitled to indemnification by the Company with respect to such Claim or Expenses), the Company, in lieu of indemnifying Indemnitee, will contribute to the payment of any and all Losses, in such proportion as is fair and reasonable in light of all of the circumstances in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Claim or Expenses or (ii) the relative fault of the Company (and its other directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

  1. Advancement of Expenses. Subject to the condition and limitations of this Agreement, the Company shall advance to or on behalf of Indemnitee, prior to the final disposition of any Claim by final adjudication to which there are no further rights of appeal, any and all Expenses actually and reasonably paid or incurred by Indemnitee in connection with any Claim arising out of an Indemnifiable Event. Indemnitee’s right to such advancement is not subject to the satisfaction of any standard of conduct. Without limiting the generality or effect of the foregoing, within five (5) business days after any request by Indemnitee, the Company shall, in accordance with such request, (a) pay such Expenses on behalf of Indemnitee, (b) advance to Indemnitee funds in an amount sufficient to pay such Expenses, or (c) reimburse Indemnitee for such Expenses. In connection with any request for Expense Advances, Indemnitee shall not be required to provide any documentation or information to the extent that the provision thereof would undermine or otherwise jeopardize attorney-client privilege. In connection with any request for Expense Advances, Indemnitee shall execute and deliver to the Company an undertaking (which shall be accepted without reference to Indemnitee’s ability to repay the Expense Advances) substantially in the form attached hereto as Exhibit A, to repay any amounts paid, advanced, or reimbursed by the Company for such Expenses to the extent that it is ultimately determined, following the final disposition of such Claim, that Indemnitee is not entitled to indemnification hereunder. Indemnitee’s obligation to reimburse the Company for Expense Advances shall be unsecured and no interest shall be charged thereon.

  2. Indemnification for Expenses in Enforcing Rights. To the fullest extent allowable under Delaware law, the Company shall also indemnify against, and, if requested by Indemnitee, shall advance to Indemnitee subject to and in accordance with Section 4, any Expenses actually and reasonably paid or incurred by Indemnitee in connection with any action or proceeding by Indemnitee for indemnification or reimbursement or advance payment of Expenses by the Company under any provision of this Agreement, or under any other agreement or provision of the Constituent Documents now or hereafter in effect relating to Claims relating to Indemnifiable Events. However, in the event that Indemnitee is ultimately determined not to be entitled to such indemnification in whole or in part, as the case may be, then all amounts advanced under this Section 5 shall be repaid in the same proportion as the those amounts to which the Indemnitee is determined not to be entitled relative to the total amounts claimed by Indemnitee in such action or proceeding. Indemnitee shall also be required to reimburse the Company in the event that a final judicial determination is made that such action brought by Indemnitee was frivolous or not made in good faith.

    4

  3. Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for a portion of any Losses in respect of a Claim related to an Indemnifiable Event but not for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled and to all Expenses incurred in connection with defending such Claim.

  4. Notification and Defense of Claims.

(a) Notification of Claims. Indemnitee shall notify the Company in writing as soon as practicable of any Claim which relates to an Indemnifiable Event and for which Indemnitee is seeking indemnification or for which Indemnitee is seeking Expense Advances, including a brief description (based upon information then available to Indemnitee) of the nature of, and the facts underlying, such Claim. The failure by Indemnitee to timely notify the Company hereunder shall not relieve the Company from any liability hereunder except that the Company shall not be liable to indemnify Indemnitee under this Agreement with respect to any judicial award in a Claim related to an Indemnifiable Event if the Company was not given a reasonable and timely opportunity to participate at its expense in the defense of such Claim. If at the time of the receipt of such notice, the Company has directors’ and officers’ liability insurance in effect under which coverage for Claims related to Indemnifiable Events is potentially available, the Company shall give prompt written notice to the applicable insurers in accordance with the procedures set forth in the applicable policies and shall take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable in connection with such Claim in accordance with the terms of such policy. The Company shall provide to Indemnitee a copy of such notice delivered to the applicable insurers, and copies of all subsequent correspondence between the Company and such insurers regarding the Claim, in each case substantially concurrently with the delivery or receipt thereof by the Company. The Company will cooperate with Indemnitee in making any supplemental claims against any directors’ and officers’ or other management liability insurance policy maintained by the Company and potentially providing coverage to Indemnitee. The failure or refusal of any insurer or insurance policy described in this Section 7(a) to pay shall not affect or impair the obligations of the Company under this Agreement.

(b) Defense of Claims. The Company shall be entitled to participate in the defense of any Claim relating to an Indemnifiable Event at its own expense and, except as otherwise provided below, to the extent the Company so wishes, it may assume the defense thereof with counsel reasonably satisfactory to Indemnitee. After notice from the Company to Indemnitee of its election to assume the defense of any such Claim, the Company shall not be liable to Indemnitee under this Agreement or otherwise for any Expenses subsequently directly incurred by Indemnitee in connection with Indemnitee’s defense of such Claim other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ its own legal counsel in such Claim, but all Expenses related to such counsel incurred after notice from the Company of its assumption of the defense shall be at Indemnitee’s own expense; provided, however, that if (i) Indemnitee’s employment of its own legal counsel has been authorized by the Company, (ii) Indemnitee has reasonably determined that there may be a conflict of interest between Indemnitee and the Company in the defense of such Claim, (iii) after a Change in Control, Indemnitee’s employment of its own counsel has been approved by the Independent Counsel or (iv) the Company shall not in fact have employed counsel to assume the defense of such Claim, then Indemnitee shall be entitled to retain its own separate counsel (but not more than one (1) law firm plus, if applicable, local counsel in respect of any such Claim, to the extent necessary and then only one (1) such local counsel per jurisdiction) and all Expenses related to such separate counsel shall be borne by the Company pursuant to the terms of this Agreement; provided further, that in all such events, Indemnitee and its counsel will not unreasonably interfere with the conduct of the defense by the Company or any Claim for which the Company has assumed the defense pursuant to this Section 7(b).

5
  1. Procedure upon Application for Indemnification. In order to obtain indemnification pursuant to this Agreement, Indemnitee shall submit to the Company a written request therefor, including in such request such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of the Claim; provided, that documentation and information need not be so provided to the extent that the provision thereof would undermine or otherwise jeopardize attorney-client privilege or work product protection. Indemnification shall be made insofar as the Company determines Indemnitee is entitled to indemnification in accordance with Section 9 below.

  2. Determination of Right to Indemnification.

(a) Mandatory Indemnification; Indemnification as a Witness.

(i) To the extent that Indemnitee shall have been successful on the merits or otherwise in defense of any Claim relating to an Indemnifiable Event or any portion thereof or in defense of any issue or matter therein, including without limitation dismissal without prejudice, Indemnitee shall be indemnified against all Losses relating to such Claim in accordance with Section 3 to the fullest extent allowable by Delaware law and no Standard of Conduct Determination will be required.

(ii) To the extent that Indemnitee’s involvement in a Claim relating to an Indemnifiable Event is limited to Indemnitee’s preparation and service as a witness, and not as a party, the Indemnitee shall be indemnified against all Losses incurred in connection therewith to the fullest extent allowable by Delaware law and no Standard of Conduct Determination will be required.

(b) Standard of Conduct. To the extent that the provisions of Section 9(a) are inapplicable to a Claim related to an Indemnifiable Event that shall have been finally disposed of, any determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law that is a legally required condition to indemnification of Indemnitee hereunder against Losses relating to such Claim and any determination that Expense Advances must be repaid to the Company (a “Standard of Conduct Determination”) shall be made as follows:

(i) if no Change in Control has occurred, (A) by a majority vote of the Disinterested Directors, even if less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum or (C) if there are no such Disinterested Directors or if Indemnitee so requests, by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee; and

(ii) if a Change in Control shall have occurred, (A) if the Indemnitee so requests in writing, by a majority vote of the Disinterested Directors, even if less than a quorum of the Board or (B) otherwise, by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee.

The Company shall indemnify and hold harmless Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five (5) business days of such request, any and all Expenses incurred by Indemnitee in cooperating with the person or persons making such Standard of Conduct Determination.

(c) Making the Standard of Conduct Determination. The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required under Section 9(b) to be made as promptly as practicable. If the person or persons designated to make the Standard of Conduct Determination under Section 9(b) has not made a determination within 30 days after the later of (A) receipt by the Company of a written request from Indemnitee for indemnification pursuant to Section 8 (the date of such receipt being the “Notification Date”) and (B) the selection of an Independent Counsel, if such determination is to be made by Independent Counsel, then Indemnitee shall be deemed to have satisfied the applicable standard of conduct; provided that such 30 days may be extended for a reasonable time, not to exceed an additional 30 days, if the person or persons making such determination in good faith requires such additional time to obtain or evaluate information relating thereto. Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of any Claim.

6

(d) Payment of Indemnification. If, in regard to any Losses:

(i) Indemnitee shall be entitled to indemnification pursuant to Section 9(a);

(ii) no Standard of Conduct Determination is legally required as a condition to indemnification of Indemnitee hereunder; or

(iii) Indemnitee has been determined or deemed pursuant to Section 9(b) or Section 9(c) to have satisfied the Standard of Conduct Determination,

then the Company shall pay to Indemnitee, within five (5) business days after the later of (A) the Notification Date or (B) the earliest date on which the applicable criterion specified in clause (i), (ii) or (iii) is satisfied, an amount equal to such Losses.

(e) Selection of Independent Counsel for Standard of Conduct Determination. If a Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 9(b)(i) or Section 9(b)(ii), the Independent Counsel shall be selected by Indemnitee, and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. The Company may, within 30 days after receiving written notice of selection from the Indemnitee, deliver to the Indemnitee a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not satisfy the criteria set forth in the definition of “Independent Counsel” in Section 1(l), and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person or firm so selected shall act as Independent Counsel. If such written objection is properly and timely made and substantiated, (i) the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit; and (ii) Indemnitee may, at its option, select an alternative Independent Counsel and give written notice to the Company advising the Company of the identity of the alternative Independent Counsel so selected, in which case the provisions of the two (2) immediately preceding sentences, the introductory clause of this sentence and numbered clause (i) of this sentence shall apply to such subsequent selection and notice. If applicable, the provisions of clause (ii) of the immediately preceding sentence shall apply to successive alternative selections. If no Independent Counsel that is permitted under the foregoing provisions of this Section 9(e) to make the Standard of Conduct Determination shall have been selected within 30 days Indemnitee gives its initial notice pursuant to this Section 9(e), Indemnitee may petition the Court of Chancery of the State of Delaware (“Delaware Court”) to resolve any objection which shall have been made by the Company to Indemnitee’s selection of Independent Counsel and/or to appoint as Independent Counsel a person to be selected by the Court or such other person as the Court shall designate, and the person or firm with respect to whom all objections are so resolved or the person or firm so appointed will act as Independent Counsel. In all events, the Company shall pay all of the reasonable fees, costs and expenses of the Independent Counsel incurred in connection with the Independent Counsel’s determination pursuant to Section 9(b).

7

(f) Presumptions and Defenses.

(i) Indemnitee’s Entitlement to Indemnification. In making any Standard of Conduct Determination, the person or persons making such determination shall presume that Indemnitee has satisfied the applicable standard of conduct and is entitled to indemnification, and the Company shall have the burden of proof to overcome that presumption and establish that Indemnitee is not so entitled. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by the Indemnitee in the Delaware Court. No determination by the Company (including by its directors or any Independent Counsel) that Indemnitee has not satisfied any applicable standard of conduct may be used as a defense to any legal proceedings brought by Indemnitee to secure indemnification or reimbursement or advance payment of Expenses by the Company hereunder or create a presumption that Indemnitee has not met any applicable standard of conduct.

(ii) Reliance as a Safe Harbor. For purposes of this Agreement, and without creating any presumption as to a lack of good faith if the following circumstances do not exist, Indemnitee shall be deemed to have acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company if Indemnitee’s actions or omissions to act are taken in good faith reliance upon the records of the Company, including its financial statements, or upon information, opinions, reports or statements furnished to Indemnitee by the officers or employees of the Company or any of its subsidiaries in the course of their duties, or by committees of the Board or by any other Person (including legal counsel, accountants and financial advisors) as to matters Indemnitee reasonably believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Company. In addition, the knowledge and/or actions, or failures to act, of any director, officer, agent or employee of the Company shall not be imputed to Indemnitee for purposes of determining the right to indemnity hereunder.

(iii) No Other Presumptions. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, will not create a presumption that Indemnitee did not meet any applicable standard of conduct or have any particular belief, or that indemnification hereunder is otherwise not permitted.

(iv) Defense to Indemnification and Burden of Proof. It shall be a defense to any action brought by Indemnitee against the Company to enforce this Agreement (other than an action brought to enforce a claim for Losses incurred in defending against a Claim related to an Indemnifiable Event in advance of its final disposition) that it is not permissible under applicable law for the Company to indemnify Indemnitee for the amount claimed. In connection with any such action or any related Standard of Conduct Determination, the burden of proving such a defense or that the Indemnitee did not satisfy the applicable standard of conduct shall be on the Company; provided, however, that the foregoing shall not limit any obligations of the Company to contribute to the payment of Losses pursuant to Section 3 of this Agreement.

  1. Exclusions from Indemnification. Notwithstanding anything in this Agreement to the contrary, the Company shall not be obligated to:

(a) indemnify or advance funds to Indemnitee for Expenses or Losses with respect to proceedings initiated by Indemnitee, including any proceedings against the Company or its directors, officers, employees or other indemnitees and not by way of defense, except:

(i) proceedings referenced in Section 5 above, subject to the conditions and limitations of Section 5; or

(ii) where the Board has consented to the initiation of such proceedings;

8

(b) indemnify Indemnitee if a final decision by a court of competent jurisdiction determines that such indemnification is prohibited by applicable law;

(c) indemnify Indemnitee for the disgorgement of profits arising from the purchase or sale by Indemnitee of securities of the Company in violation of Section 16(b) of the Exchange Act, or any similar successor statute; or

(d) indemnify or advance funds to Indemnitee for Indemnitee’s reimbursement to the Company of any bonus or other incentive-based or equity-based compensation previously received by Indemnitee or payment of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements under Section 304 of the Sarbanes-Oxley Act of 2002 in connection with an accounting restatement of the Company or the payment to the Company of profits arising from the purchase or sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act).

  1. Settlement of Claims. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid in settlement of any threatened or pending Claim related to an Indemnifiable Event effected without the Company’s prior written consent, which shall not be unreasonably withheld. The Company shall not settle any Claim related to an Indemnifiable Event in any manner (a) that would impose any Losses on the Indemnitee without the Indemnitee’s prior written consent, unless such Losses are fully indemnified by the Company; or (b) that includes equitable remedies or does not include a complete and unconditional release of Indemnitee for all liability related to the relevant Claims.

  2. Duration. All agreements and obligations of the Company contained herein shall continue during the period that Indemnitee is a director or officer of the Company (or is serving at the request of the Company as a director, officer, employee, member, trustee or agent of another Enterprise) and shall continue thereafter (a) so long as Indemnitee may be subject to any possible Claim relating to an Indemnifiable Event (including any rights of appeal thereto) and (b) throughout the pendency of any proceeding (including any rights of appeal thereto) commenced by Indemnitee to enforce or interpret his or her rights under this Agreement (to the extent such amounts are indemnifiable pursuant to this Agreement), even if, in either case, he or she may have ceased to serve in such capacity at the time of any such Claim or proceeding.

  3. Non-Exclusivity. The rights of Indemnitee hereunder will be in addition to any other rights Indemnitee may have under the Constituent Documents, the General Corporation Law of the State of Delaware, any other contract or otherwise (collectively, “Other Indemnity Provisions”); provided, however, that (a) to the extent that Indemnitee otherwise would have any greater right to indemnification under any Other Indemnity Provision, Indemnitee will be deemed to have such greater right hereunder and (b) to the extent that any change is made to any Other Indemnity Provision which permits any greater right to indemnification than that provided under this Agreement as of the date hereof, Indemnitee will be deemed to have such greater right hereunder.

  4. Liability Insurance. For the duration of Indemnitee’s service as a director or officer of the Company, and thereafter for so long as Indemnitee shall be subject to any pending Claim relating to an Indemnifiable Event, the Company shall use commercially reasonable efforts (taking into account the scope and amount of coverage available relative to the cost thereof) to maintain or continue to maintain in effect policies of directors’ and officers’ liability insurance providing coverage that is at least substantially comparable in scope and amount to that provided by the Company’s current policies of directors’ and officers’ liability insurance. In all policies of directors’ and officers’ liability insurance maintained by the Company, Indemnitee shall be named or otherwise treated as an insured in such a manner as to provide Indemnitee the same rights and benefits as are provided to the most favorably insured of persons in comparable roles relative to the Company. Upon request, the Company will provide to Indemnitee copies of all directors’ and officers’ liability insurance applications, binders, policies, declarations, endorsements and other related materials.

    9

  5. No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment to Indemnitee in respect of any Losses to the extent Indemnitee has otherwise received payment under any insurance policy, the Constituent Documents, Other Indemnity Provisions or otherwise (including any other indemnification agreement or commitment with any other Person) of the amounts otherwise indemnifiable by the Company hereunder.

  6. Subrogation. In the event of payment to Indemnitee under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee. Indemnitee shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights. The Company shall pay or reimburse all Expenses actually and reasonably incurred by Indemnitee in connection with such subrogation.

  7. Amendments. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be binding unless in the form of a writing signed by the party against whom enforcement of the waiver is sought, and no such waiver shall operate as a waiver of any other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising any right or remedy hereunder shall constitute a waiver thereof.

  8. Binding Effect. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company), assigns, spouses, heirs and personal and legal representatives. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part of the business and/or assets of the Company, by written agreement in form and substances satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

  9. Severability. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any portion thereof) are held by a court of competent jurisdiction to be invalid, illegal, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by law. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

  10. Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if delivered by hand, against receipt, or mailed, by postage prepaid, certified or registered mail or email:

(a) if to Indemnitee, to the address set forth on the signature page hereto.

The Company and Indemnitee hereby irrevocably and unconditionally: (a) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court and not in any other state or federal court in the United States, (b) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement and (c) waive, and agree not to plead or make, any claim that the Delaware Court lacks venue or that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.

Section3 Exchange for SPAC Warrants in connection with a SPAC Transaction

(1) From<br> and after the SPAC Closing Date pursuant to a SPAC Transaction, upon<br> any subsequent exercise of the Warrants, the Holder shall have the right to receive, for<br> each share of the Common Stock that otherwise would have been issuable upon such exercise<br> immediately prior to the occurrence of the SPAC Transaction, such number of shares of Resulting<br> Issuer Stock and any additional consideration (collectively, the “SPAC<br> Consideration”) receivable as a result of such SPAC<br> Transaction by a holder of one (1) share of Common Stock prior to such SPAC Transaction.<br> For purposes of any such exercise, the determination of the Exercise Price following the<br> SPAC Closing Date shall be appropriately adjusted to apply to such SPAC Consideration based<br> on the amount of SPAC Consideration issuable in respect of one (1) share of Common Stock<br> in such SPAC Transaction, and the Company shall apportion the Exercise Price among the SPAC<br> Consideration in a reasonable manner reflecting the relative value of any different components<br> of the SPAC Consideration. The Company shall cause the Resulting Issuer in a SPAC Transaction<br> in which the Company is not the surviving entity to assume in writing the obligations of<br> the Company to issue Resulting Issuer Stock upon exercise of this Warrant and may, at the<br> option of the Resulting Issuer, elect to deliver to the Holder in exchange for this Warrant<br> Certificate a security of the Resulting Issuer evidenced by a written instrument (the<br> “SPAC Warrant Certificate”)<br> substantially similar in economic<br> substance to this Warrant Certificate that is exercisable for a corresponding number of shares<br> of capital stock of such Resulting Issuer equivalent to the number of shares of Common Stock<br> issuable upon exercise of the unexercised Warrants under this Warrant Certificate exercisable<br> prior to such SPAC Transaction, and with an exercise price which applies the Exercise Price<br> hereunder to such shares of capital stock (but taking into account the relative value of<br> the Common Stock pursuant to such SPAC Transaction and the value of such shares of capital<br> stock, such number of shares of capital stock and such exercise price being for the purpose<br> of protecting the economic value of the unexercised Warrants outstanding immediately prior<br> to the consummation of such SPAC Transaction). Upon the Resulting Issuer’s delivery<br> of a SPAC Warrant Certificate exercisable for the number of shares of the Resulting Issuer<br> Stock and an adjusted Exercise Price as set forth above, this Warrant Certificate shall automatically<br> be cancelled and the Holder shall have no further rights hereunder. In the event that the<br> Resulting Issuer is not organized under the law of a jurisdiction in the United States or<br> the primary trading market of the Resulting Issuer is outside the United States, the SPAC<br> Warrant Certificate may provide for governing law, jurisdiction, venue, and ministerial and<br> administrative provisions that the Resulting Issuer determines appropriate. Upon the occurrence<br> of any such SPAC Transaction, the Resulting Issuer shall succeed to, and be substituted for<br> (so that from and after the date of such SPAC Transaction, the provisions of this Warrant<br> Certificate referring to the “Company” shall refer instead to the Resulting Issuer),<br> and may exercise every right and power of the Company as if such Resulting Issuer had been<br> named as the Company herein. Following the SPAC Closing Date, the terms “Company”<br> and “Common Stock” as used herein shall refer to the Resulting Issuer and the<br> Resulting Issuer Stock, respectively, unless the context otherwise requires.
- 5 -
(2) If<br> necessary, as a result of any SPAC Transaction, appropriate adjustments will be made in the<br> application of the provisions of this Warrant Certificate with respect to the rights and<br> interest thereafter of the Holder to the end that the provisions of this Warrant Certificate<br> will thereafter correspondingly be made applicable as nearly as may reasonably be possible<br> in relation to any SPAC Warrant Certificate or other securities thereafter deliverable pursuant<br> to Section<br> 3(1). Pursuant to Section 3(1), the Company will seek, acting in good faith, to make adjustments<br> with respect to the issuance of a SPAC Warrant Certificate in connection with a SPAC Transaction<br> as it considers necessary and equitable. If at any time a dispute arises with respect to<br> adjustments provided for in connection with the issuance of a SPAC Warrant Certificate, such<br> dispute will be conclusively determined by the auditors of the Company or, if they are unable<br> or unwilling to act, by such other firm of independent chartered accountants as may be selected<br> by the directors of the Company and any such determination, absent manifest error, will be<br> binding upon the Company, the Holder and shareholders of the Company. The Company will provide<br> such auditors or accountants with access to all necessary records of the Company and fees<br> payable to such accountants or auditors will be paid by the Company.
(3) Notwithstanding<br> any other provision hereof, the Company shall not be required to issue the Common Stock or,<br> using commercially reasonable efforts, cause the Resulting Issuer Stock to be issued, as<br> the case may be, if the Holder has not executed and delivered a Lock-Up Agreement prior to<br> the closing of the IPO or SPAC Closing Date, as the case may be, or has violated the terms<br> of the Lock-Up Agreement in any material respect.
--- ---

Section4 Capital Reorganization

(1) If<br> there shall be, prior to the exercise of the Warrants, any (a)<br> reorganization of the authorized capital of the Company by way of consolidation, merger,<br> sub-division, amalgamation, arrangement, reclassification or otherwise, including in connection<br> with a SPAC Transaction; (b) the payment of any stock dividends (other than in the ordinary<br> course of business); (c) a special distribution or rights offering; (d) the change or exchange<br> of the Common Stock or preferred stock of the Company into or with another security (other<br> than the conversion of the Common Stock or preferred stock of the Company), including in<br> connection with a SPAC Transaction; or (e) any similar event or transaction not specifically<br> contemplated by the foregoing subsections (a), (b), (c), and (d), as determined by the Company<br> in its sole discretion (in each case, a “Capital Reorganization”), then there shall automatically<br> be an adjustment, as applicable, in (i) the number and, if applicable, type of securities<br> which may be issued pursuant to this Warrant Certificate, and (ii) the Exercise Price for<br> such securities, such that the rights under this Warrant Certificate following such adjustment<br> shall thereafter be as reasonably as possible equivalent to the rights originally granted<br> hereby and such that the Holder, upon exercise of this Warrant Certificate following the<br> effective date of the Capital Reorganization, shall receive the number and type of securities<br> the Holder would have been entitled to receive if, on the effective date thereof, the Holder<br> had been the registered holder of the number of shares of Common Stock which the Holder was<br> theretofore entitled to purchase or receive upon the exercise of the Warrants.
(2) Pursuant<br> to the foregoing, the Company will make adjustments in connection with a Capital Reorganization<br> as it considers necessary and equitable, acting in good faith. If at any time a dispute arises<br> with respect to adjustments provided for in connection with a Capital Reorganization, such<br> dispute will be conclusively determined by the auditors of the Company or if they are unable<br> or unwilling to act, by such other firm of independent chartered accountants as may be selected<br> by the directors of the Company and any such determination, absent manifest error, will be<br> binding upon the Company, the Holder and shareholders of the Company. The Company will provide<br> such auditors or accountants with access to all necessary records of the Company and fees<br> payable to such accountants or auditors will be paid by the Company.

Section5 Cashless Exercise of Warrants

(1) Notwithstanding<br> anything to the contrary contained herein, and provided that the Warrants could otherwise<br> be exercised in accordance with the terms hereof, the Holder may elect to exercise the Warrants,<br> in whole or in part, without payment of the aggregate Exercise Price due on such exercise<br> (a “Cashless Exercise<br> Option”) in the manner set out in this Section 5,<br> as applicable. If the Holder elects the Cashless Exercise Option, the Holder shall provide<br> written notice of the election to the Company in the form of the Cashless Subscription Form.<br> Upon actual receipt by the Company of a Cashless Subscription Form, a certificate or confirmation<br> of book entry registration (as directed by the Holder) for the appropriate number of shares<br> of Common Stock will be delivered to the person(s) in whose name(s) the Common Stock subscribed<br> for is to be issued within five (5) Business Days of receipt of the Cashless Subscription<br> Form, such person(s) shall become a holder in respect of such shares of Common Stock with<br> effect from the date of such exercise, and, unless this Warrant Certificate has expired,<br> a new Warrant Certificate representing the unexercised balance of the Warrants, if any, or<br> all of the Warrants evidenced by this Warrant Certificate having been exercised will also<br> be issued to the Holder within such time.
(2) The<br> number of shares of Common Stock to be issued to the Holder pursuant to a Cashless Exercise<br> Option shall be determined as follows (provided, for the avoidance of doubt, that if the<br> following calculation results in a negative number, then no Common Stock shall be issuable<br> via the Cashless Exercise Option):
--- ---
X<br> = Y<br> x (A-B)
--- ---
A
Where: X<br> = the number of shares of Common Stock to be issued to the Holder upon exercising the Warrants;
--- ---

Y = the number of Warrants being exercised;

A = the Applicable Market Price per share of the Common Stock; and

B = the Exercise Price of the Warrants.

(3) To<br> the extent that this Warrant Certificate is not previously exercised in full by the Holder<br> on or prior to the Expiry Date, and if the Applicable Market Price per share of Common Stock<br> is greater than the Exercise Price with respect to the Common Stock, any such portion of<br> this Warrant Certificate that remains unexercised shall be exercised automatically in whole<br> (and not in part) at the Expiry Date (with the Exercise Price satisfied pursuant to a Cashless<br> Exercise Option in accordance with this Section<br> 5), unless the Holder provides a written instruction to the Company to allow the Warrants<br> to lapse without exercise at least three (3) days prior to the Expiry Date, and such instruction<br> will result in the termination of this Warrant Certificate. To the extent this Warrant Certificate<br> or any portion thereof is deemed automatically exercised pursuant to this Section 5(3), the<br> Company agrees to promptly notify the Holder of the number of shares of Common Stock that<br> the Holder is to receive by reason of such automatic exercise.
(4) If<br> the number of shares of Common Stock to be issued to the Holder exercising its Warrants on<br> a cashless basis in accordance with Section<br> 5(2) above results in a fractional number, the number of shares of Common Stock to be issued<br> to the Holder shall be rounded down to the nearest whole number with compensation to the<br> Holder therefor for the fractional share of Common Stock to be paid in accordance with Section<br> 2.
