Exhibit 10.12

EMPLOYMENT AGREEMENT
This Employment Agreement (this “Agreement”) is made between Prime Medicine, Inc., a Delaware corporation (the “Company”), and Meredith Goldwasser, ScD (the “Executive”) and is effective as of the closing of the Company’s first underwritten public offering of its equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Effective Date”). Except with respect to the Restrictive Covenants Agreement and the Equity Documents (each as defined below) and subject to Section 11, this Agreement supersedes in all respects all prior agreements between the Executive and the Company regarding the subject matter herein, including without limitation (i) the employment agreement between the Executive and the Company executed September 6, 2020 (the “Prior Agreement”), and (ii) any other offer letter, employment agreement or severance agreement. 
WHEREAS, the Company desires to continue to employ the Executive and the Executive desires to continue to be employed by the Company on the new terms and conditions contained herein.
NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:
1.    Employment.
(a)    Term. The Company shall employ the Executive and the Executive shall be employed by the Company pursuant to this Agreement commencing as of the Effective Date and continuing until such employment is terminated in accordance with the provisions hereof (the “Term”). The Executive’s employment with the Company shall continue to be “at will,” meaning that the Executive’s employment may be terminated by the Company or the Executive at any time for any or no reason, subject to the terms of this Agreement.
(b)    Position and Duties. The Executive shall serve as the Senior Vice President, Strategy and Corporate Operations of the Company and shall report to the Chief Executive Officer of the Company. This is a full-time position, and the Executive shall not engage in any other employment, consulting or other business activities (whether full-time or part-time), except as expressly authorized in writing by the Company’s Chief Executive Officer (the “CEO”). Notwithstanding the foregoing, the Executive may engage in professional and educational organizations, religious, charitable and other community activities (as well as manage the Executive’s personal investments) so long as any outside activities do not interfere or conflict with the Executive’s obligations to the Company. Any compensation received by the Executive for outside board service or other activities shall belong solely to the Executive, and the Company shall have no right to such compensation.
(c)    The Executive’s primary work location will continue to be at the Company’s office, which is presently located in Cambridge, Massachusetts, provided that the Executive may be required to travel for business, consistent with the Company’s business needs.

2.    Compensation and Related Matters.
(a)    Base Salary. The Company will pay the Executive a base salary at the rate of $400,000 per year, payable in accordance with the Company’s standard payroll schedule for its executives and subject to applicable deductions and withholdings. The Executive’s base salary will be subject to periodic review and adjustments by the Board or the Compensation Committee of the Board (the “Compensation Committee”). The base salary in effect at any given time is referred to herein as the “Base Salary.”
(b)    Annual Bonus. The Executive will be eligible to receive an annual target performance bonus of 35% of the Executive’s Base Salary. The annual target performance bonus in effect at any given time is referred to herein as “Target Bonus.” The actual bonus amount is discretionary. To earn an annual bonus, the Executive must be employed by the Company as of the payment date of such bonus, except as otherwise provided herein; provided that if the Executive is terminated by the Company without Cause or the Executive resigns for Good Reason (as such terms are defined in Section 3), in either event on or after January 1 but before the date bonuses for the prior year are paid to the Company’s other executives (the “Bonus Payment Date”), the bonus amount (if any) that the Executive would have been paid if the Executive had remained employed through the Bonus Payment Date shall be paid to the Executive on the Bonus Payment Date if the Executive enters into, does not revoke and complies with the Separation Agreement (as defined below). Any annual bonus will be paid no later than March 15th of the calendar year following the calendar year to which such bonus relates.
(c)    Expenses. The Company will promptly reimburse the Executive for all reasonable business expenses incurred by the Executive in performing services hereunder, in accordance with the policies and procedures then in effect and established by the Company for its executives.
(d)    Benefits/Paid Time Off. The Executive will be eligible, subject to the terms of the applicable plans and programs, to participate in the employee benefits and insurance programs and be eligible for paid time off generally made available to the Company’s full-time executive employees. The Company reserves the right to modify, amend or cancel any of its benefits plans or programs at any time.
(e)    Equity. The equity awards held by the Executive shall continue to be governed by the terms and conditions of the Company’s applicable equity incentive plan(s) and the applicable award agreement(s) (collectively, the “Equity Documents”); provided, however, and notwithstanding anything to the contrary in any applicable option agreement or other stock-based award agreement, in the event that the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason, in each case during the Change in Control Period (as defined below), all of the then-outstanding and unvested portion of the Executive’s stock options and other stock-based awards that (A) are subject solely to time-based vesting or (B) were granted to the Executive prior to the Effective Date and are subject to performance-based vesting (the “Performance-Based Awards”) shall become fully vested and exercisable or nonforfeitable immediately as of the Date of Termination (as defined below), with any such Performance-Based Awards vesting at target. For the avoidance of doubt, (I) the 
2

forfeiture provisions upon a Change in Control described in the Plan (as defined below) shall not apply to the Executive’s equity awards that are subject to acceleration pursuant to this subsection, and (II) any stock options or other stock-based awards that are subject to performance-based vesting and that are granted to the Executive after the Effective Date shall not be subject to acceleration pursuant to this subsection, and the vesting and any acceleration of vesting of such awards (if any) will be addressed in the applicable award agreements.
3.    Termination. The Executive’s employment hereunder may be terminated without any breach of this Agreement under the following circumstances:
(a)    Death. The Executive’s employment hereunder shall terminate upon death.
(b)    Disability. The Company may terminate the Executive’s employment if the Executive is disabled and unable to perform or expected to be unable to perform the essential functions of the Executive’s then existing position or positions under this Agreement with or without reasonable accommodation for a period of 180 days (which need not be consecutive) in any 12-month period. If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the essential functions of the Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive. Nothing in this Section 3(b) shall be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. §12101 et seq.
(c)    Termination by the Company for Cause. The Company may terminate the Executive’s employment hereunder for Cause. For purposes of this Agreement, “Cause” shall mean any of the following:
(i)    the Executive’s dishonest statements or acts with respect to the Company or any affiliate of the Company, or any current or prospective customers, suppliers, vendors or other third parties with which such entity does business that results in or is reasonably anticipated to result in material harm to the Company;
(ii)    the Executive’s commission of (A) a felony or (B) any misdemeanor involving moral turpitude, deceit, dishonesty or fraud;
(iii)    the Executive’s refusal to perform the Executive’s assigned duties and responsibilities, which refusal to perform continues, in the reasonable judgment of the CEO, 
3

for 30 days after written notice given to the Executive by the CEO describing such refusal in reasonable detail;
(iv)    the Executive’s gross negligence, willful misconduct or insubordination with respect to the Company that results in or is reasonably anticipated to result in harm to the Company;
(v)    the Executive’s material violation of any material provision of any written employment policies or any agreement(s) between the Executive and the Company, including any agreement relating to noncompetition, nonsolicitation, nondisclosure and/or assignment of inventions; or
(vi)    the Executive’s failure to cooperate with a bona fide internal investigation or an investigation by regulatory or law enforcement authorities, after being instructed by the Company to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to cooperate or to produce documents or other materials in connection with such investigation.
(d)    Termination by the Company without Cause. The Company may terminate the Executive’s employment hereunder at any time without Cause. Any termination by the Company of the Executive’s employment under this Agreement which does not constitute a termination for Cause under Section 3(c) and does not result from the death or disability of the Executive under Section 3(a) or (b) shall be deemed a termination without Cause.
(e)    Termination by the Executive. The Executive may terminate employment hereunder at any time for any reason, including but not limited to, Good Reason. For purposes of this Agreement, “Good Reason” shall mean that the Executive has complied with the Good Reason Process (hereinafter defined) following the occurrence of any of the following events without the Executive’s consent (each, a “Good Reason Condition”):
(i)    following a Change in Control, a material diminution in the Executive’s responsibilities, authority or duties, except that a suspension of the Executive’s responsibilities, authority and/or duties for the Company during any portion of a bona fide internal investigation or an investigation by regulatory or law enforcement authorities shall not be a Good Reason Condition; 
(ii)    a material diminution in the Executive’s Base Salary except for across-the-board salary reductions based on the Company’s financial performance similarly affecting all or substantially all senior management employees of the Company; 
(iii)    a change of more than 50 miles in the geographic location at which the Executive is required to provide services to the Company; or 
(iv)    a material breach of this Agreement or any equity award by the Company.
4

The “Good Reason Process” shall mean that: 
(i)    the Executive reasonably determines that a Good Reason Condition has occurred; 
(ii)    the Executive notifies the Company in writing of the occurrence of the Good Reason Condition within 30 days of the Executive’s knowledge of such condition; 
(iii)    the Executive cooperates in good faith with the Company’s efforts, for a period of not less than 30 days following such notice (the “Cure Period”), to remedy the Good Reason Condition; 
(iv)    notwithstanding such efforts, the Good Reason Condition continues to exist at the end of the Cure Period; and 
(v)    the Executive terminates employment within 30 days after the end of the Cure Period.
If the Company cures the Good Reason Condition during the Cure Period, Good Reason shall be deemed not to have occurred.
4.    Matters related to Termination.
(a)    Notice of Termination. Except for termination as specified in Section 3(a), any termination of the Executive’s employment by the Company or any such termination by the Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon.
(b)    Date of Termination. “Date of Termination” shall mean: (i) if the Executive’s employment is terminated by death, the date of death; (ii) if the Executive’s employment is terminated on account of disability under Section 3(b) or by the Company for Cause under Section 3(c), the date on which Notice of Termination is given; (iii) if the Executive’s employment is terminated by the Company without Cause under Section 3(d), the date on which a Notice of Termination is given or the date otherwise specified by the Company in the Notice of Termination; (iv) if the Executive’s employment is terminated by the Executive under Section 3(e) other than for Good Reason, 30 days after the date on which a Notice of Termination is given, and (v) if the Executive’s employment is terminated by the Executive under Section 3(e) for Good Reason, the date on which a Notice of Termination is given after the end of the Cure Period. Notwithstanding the foregoing, in the event that the Executive gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not result in a termination by the Company for purposes of this Agreement.
5

(c)    Accrued Obligations. If the Executive’s employment with the Company is terminated for any reason, the Company shall pay or provide to the Executive (or to the Executive’s authorized representative or estate) (i) any Base Salary earned through the Date of Termination; (ii) unpaid expense reimbursements (subject to, and in accordance with, Section 2(c) of this Agreement); and (iii) any vested benefits the Executive may have under any employee benefit plan of the Company through the Date of Termination, which vested benefits shall be paid and/or provided in accordance with the terms of such employee benefit plans. The payments and benefits due to the Executive under this Section 4(c) are collectively referred to herein as the “Accrued Obligations.”
(d)    Resignation of All Other Positions. To the extent applicable, the Executive shall be deemed to have resigned from all officer and board member positions that the Executive holds with the Company or any of its respective subsidiaries and affiliates upon the termination of the Executive’s employment for any reason. The Executive shall execute any documents in reasonable form as may be requested to confirm or effectuate any such resignations.
5.    Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason Outside the Change in Control Period. If the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d), or the Executive terminates employment for Good Reason as provided in Section 3(e), in each case outside of the Change in Control Period, then, in addition to the Accrued Obligations, and subject to (i) the Executive signing a separation agreement and release in a form and manner reasonably satisfactory to the Company, which shall include, without limitation, a general release of claims against the Company and all related persons and entities that shall not release the Executive’s rights under this Agreement, a reaffirmation of the Executive’s Continuing Obligations (as defined below), and, in the Company’s sole discretion, a one year post-employment noncompetition agreement, and shall provide that if the Executive breaches in any material respect the Continuing Obligations, all payments of the Severance Amount (as defined below) shall immediately cease (the “Separation Agreement”), and (ii) the Separation Agreement becoming irrevocable, all within 60 days after the Date of Termination (or such shorter period as set forth in the Separation Agreement), which shall include a seven (7) business day revocation period:
(a)    the Company shall pay the Executive an amount equal to the sum of (i) six (6) months of the Executive’s then-current Base Salary plus (ii) 0.5 times the Executive’s Target Bonus for the then-current year (the “Severance Amount”); and
(b)    subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall pay to the group health plan provider or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the six (6) month anniversary of the Date of Termination; (B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group 
6

medical plan; or (C) the cessation of the Executive’s health continuation rights under COBRA; provided, however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above. Such payments to the Executive shall be subject to tax-related deductions and withholdings and paid on the Company’s regular payroll dates.
The amounts payable under Section 5, to the extent taxable, shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over six (6) months commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payments, to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin to be paid in the second calendar year by the last day of such 60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following the Date of Termination. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). For the avoidance of doubt, the Executive shall not be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under this Section 5, subject to the terms of this Agreement.
6.    Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason during the Change in Control Period. The provisions of this Section 6 shall apply in lieu of, and expressly supersede, the provisions of Section 5 if (i) the Executive’s employment is terminated either (a) by the Company without Cause as provided in Section 3(d), or (b) by the Executive for Good Reason as provided in Section 3(e), and (ii) the Date of Termination occurs during the Change in Control Period. These provisions shall terminate and be of no further force or effect after the Change in Control Period.
(a)    If the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d) or the Executive terminates employment for Good Reason as provided in Section 3(e) and in each case the Date of Termination occurs during the Change in Control Period, then, in addition to the Accrued Obligations, and subject to the signing of the Separation Agreement by the Executive and the Separation Agreement becoming fully effective, all within the time frame set forth in the Separation Agreement but in no event more than 60 days after the Date of Termination:
(i)    the Company shall pay the Executive a lump sum in cash in an amount equal to the sum of (A) six (6) months of the Executive’s then-current Base Salary (or the Executive’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) 0.5 times the Executive’s Target Bonus for the then-current year (or the Executive’s Target Bonus in effect immediately prior to the Change in Control, if higher) (the “Change in Control Payment”); and
7

(ii)    subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under COBRA, the Company shall pay to the group health plan provider or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the six (6) month anniversary of the Date of Termination; (B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group medical plan; or (C) the cessation of the Executive’s health continuation rights under COBRA; provided, however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above. Such payments to the Executive shall be subject to tax-related deductions and withholdings and paid on the Company’s regular payroll dates.
The amounts payable under this Section 6(a), to the extent taxable, shall be paid or commence to be paid within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payments to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall be paid or commence to be paid in the second calendar year by the last day of such 60-day period. For the avoidance of doubt, the Executive shall not be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under this Section 6, subject to the terms of this Agreement.
(b)    Additional Limitation.
(i)    Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Code, and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which the Executive becomes subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction shall only occur if it would result in the Executive receiving a higher After Tax Amount (as defined below) than the Executive would receive if the Aggregate Payments were not subject to such reduction. In such event, the Aggregate Payments shall be reduced in the following order, in each case, in reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction that is subject to Section 280G of the Code: (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of 
8

benefits; provided that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c).
(ii)    For purposes of this Section 6(b), the “After Tax Amount” means the amount of the Aggregate Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of the Executive’s receipt of the Aggregate Payments. For purposes of determining the After Tax Amount, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. 
(iii)    The determination as to whether a reduction in the Aggregate Payments shall be made pursuant to Section 6(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or the Executive. Any determination by the Accounting Firm shall be binding upon the Company and the Executive.
(c)    Definitions. For purposes of this Agreement:
(i)    “Change in Control” shall mean a “Sale Event” as defined in the Company’s 2022 Stock Option and Incentive Plan, as the same may be amended from time to time (the “Plan”).
(ii)    “Change in Control Period” shall mean the period beginning on the date of the consummation of the first event constituting a Change in Control (the “Closing Date”) and ending on the 12 month anniversary of the Closing Date.
7.    Section 409A.
(a)    Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement or otherwise on account of the Executive’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Executive’s separation from service, or (B) the Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up 
9

payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 
(b)    All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Executive during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses). Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.
(c)    To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).
(d)    The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with or are exempt from Section 409A of the Code. Each payment pursuant to this Agreement or the Restrictive Covenants Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.
(e)    The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.
8.    Continuing Obligations. 
(a)    Restrictive Covenants Agreement. As a condition of employment, and in exchange for the benefits set forth in this Agreement, to which the Executive was not previously entitled, the Executive is required to enter into the Amendment to the Employee Confidentiality, Assignment and Nonsolicitation Agreement attached hereto as Exhibit A, which adds a post-employment noncompetition agreement to the Employee Confidentiality, Assignment and Nonsolicitation Agreement between the Executive and the Company dated as of September 6, 
10

2020 (as amended, the “Restrictive Covenants Agreement”). For purposes of this Agreement, the obligations in this Section 8 and those that arise in the Restrictive Covenants Agreement and any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.” For the avoidance of doubt, all restrictive covenants obligations are supplemental to one another, and in the event of any conflict between restrictive covenants obligations, the most restrictive provision that is enforceable shall govern. In the event the Executive is entitled to both payments pursuant to the Restrictive Covenants Agreement and severance payments pursuant to Section 5 or Section 6 of this Agreement, then the severance payments pursuant to Section 5 or Section 6 of this Agreement received in any calendar year will be reduced by the amount the Executive is paid in the same such calendar year pursuant to the Restrictive Covenants Agreement.
(b)    Third-Party Agreements and Rights. The Executive represents to the Company that the Executive’s execution of this Agreement, the Executive’s employment with the Company and the performance of the Executive’s proposed duties for the Company will not violate any obligations the Executive may have to any previous employer or other party. In the Executive’s work for the Company, the Executive will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party.
(c)    Litigation and Regulatory Cooperation. During and for 36 months after the Executive’s employment, the Executive shall cooperate reasonably with the Company in (i) the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while the Executive was employed by the Company, and (ii) the investigation, whether internal or external, of any matters about which the Company believes the Executive may have knowledge or information. The Executive’s reasonable cooperation in connection with such claims, actions or investigations shall include, but not be limited to, being available to meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During and after the Executive’s employment, the Executive also shall cooperate reasonably with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company. The Company shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 8(c).
(d)    Relief. The Executive agrees that it would be difficult to measure any damages caused to the Company which might result from any breach by the Executive of the Continuing Obligations, and that in any event money damages would be an inadequate remedy for any such breach. Accordingly, the Executive agrees that if the Executive breaches, or proposes to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable 
11

relief to restrain any such breach without showing or proving any actual damage to the Company.
9.    Consent to Jurisdiction. The parties hereby consent to the jurisdiction of the state and federal courts of the Commonwealth of Massachusetts. Accordingly, with respect to any such court action, the Executive (a) submits to the exclusive personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process.
10.    Waiver of Jury Trial. Each of the Executive and the Company irrevocably and unconditionally WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, INCLUDING WITHOUT LIMITATION THE EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT. 
11.    Integration. This Agreement, together with the Restrictive Covenants Agreement, constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements between the parties concerning such subject matter, including the Prior Agreement, provided that the Equity Documents remain in full force and effect.
12.    Withholding; Tax Effect. All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. The Executive hereby acknowledges that the Company does not have a duty to design its compensation policies in a manner that minimizes the Executive’s tax liabilities, and the Executive will not make any claim against the Company or the Board related to tax liabilities arising from the Executive’s compensation.
13.    Assignment; Successors and Assigns. Neither the Executive nor the Company may make any assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement (including the Restrictive Covenants Agreement) without the Executive’s consent to any affiliate or to any person or entity with whom the Company shall hereafter effect a reorganization or consolidation, into which the Company merges or to whom it transfers all or substantially all of its properties or assets; provided, further that if the Executive remains employed or becomes employed by the Company, the purchaser or any of their affiliates in connection with any such transaction, then the Executive shall not be entitled to any payments or benefits pursuant to Section 5 or Section 6 of this Agreement or any accelerated vesting pursuant to Section 2(e) of this Agreement solely as a result of such transaction (except that, for the avoidance of doubt, the Executive will be eligible for double trigger accelerated vesting as set forth herein). This Agreement shall inure to the benefit of and be binding upon the Executive and the Company, and each of the Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns. In the event of the Executive’s death after the Executive’s termination of employment but prior to the completion by the Company of all payments due to the Executive under this Agreement, the 
12

Company shall continue such payments to the Executive’s beneficiary designated in writing to the Company prior to the Executive’s death (or to the Executive’s estate, if the Executive fails to make such designation).
14.    Enforceability. If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.
15.    Survival. The provisions of this Agreement (and the Restrictive Covenants Agreement and the Equity Documents) shall survive the termination of this Agreement and/or the termination of the Executive’s employment to the extent necessary to effectuate the terms contained herein.
16.    Waiver. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.
17.    Notices. Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed in writing with the Company or, in the case of the Company, at its main offices, attention of the CEO. Notices, requests, demands and other communications provided for by this Agreement shall also be sufficient if sent by email to the Company email address of the Executive or, in the case of Company, the Company email address of the CEO, with confirmation of receipt.
18.    Amendment. This Agreement may be amended or modified only by a written instrument signed by the Executive and by a duly authorized representative of the Company.
19.    Effect on Other Plans and Agreements. An election by the Executive to resign for Good Reason under the provisions of this Agreement shall not be deemed a voluntary termination of employment by the Executive for the purpose of interpreting the provisions of any of the Company's benefit plans, programs or policies. Nothing in this Agreement shall be construed to limit the rights of the Executive under the Company’s benefit plans, programs or policies except as otherwise provided in Section 8 hereof, and except that the Executive shall have no rights to any severance benefits under any Company severance pay plan, offer letter or otherwise. Except for the Restrictive Covenants Agreement, in the event that the Executive is party to an agreement with the Company providing for payments or benefits under such plan or agreement and under this Agreement, the terms of this Agreement shall govern and the Executive may receive payment under this Agreement only and not both. Further, Section 5 and Section 6 
13

of this Agreement are mutually exclusive and in no event shall the Executive be entitled to payments or benefits pursuant to both Section 5 and Section 6 of this Agreement. 
20.    Governing Law. This is a Massachusetts contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts, without giving effect to the conflict of laws principles thereof. With respect to any disputes concerning federal law, such disputes shall be determined in accordance with the law as it would be interpreted and applied by the United States Court of Appeals for the First Circuit.
21.    Counterparts. This Agreement may be executed in separate counterparts. When both counterparts are signed, they shall be treated together as one and the same document. PDF copies of signed counterparts shall be equally effective as originals.

    satisfaction of all of the conditions set forth in Section 7.3, the Company shall have the right, but not the obligation, to require the Investor, by delivering to the Investor a VWAP Purchase Notice for a VWAP Purchase, specifying in such VWAP
    Purchase Notice (a) whether such VWAP Purchase is (x) a “VWAP Purchase-Type A” (each such subscription and purchase, a “VWAP Purchase-Type A”) or (y) a “VWAP Purchase-Type B” (each such subscription and purchase, a “VWAP
        Purchase-Type B”) and (b) whether a Limit Order Continue Election or a Limit Order Discontinue Election shall apply to such VWAP Purchase, on the applicable Purchase Date therefor, to purchase a specified VWAP Purchase Share Amount, which
    shall not exceed the applicable VWAP Purchase Maximum Amount, at the applicable VWAP Purchase Price therefor on such Purchase Date in accordance with this Agreement. The Company may deliver to the Investor a VWAP Purchase Notice for a VWAP Purchase on
    any Trading Day selected by the Company as the Purchase Date for such VWAP Purchase, so long as (i) the Closing Sale Price of the Ordinary Shares on the Trading Day immediately preceding such Purchase Date is not less than the Threshold Price, and (ii)
    all Shares subject to all prior VWAP Purchases and Intraday VWAP Purchases (as applicable) pursuant to this Agreement with Purchase Share Delivery Times prior to the Purchase Date have been received by the Investor as DWAC Shares prior to the Company’s

    Company is then permitted to include in such VWAP Purchase Notice (taking into account whether the VWAP Purchase to be effected pursuant to such VWAP Purchase Notice is specified by the Company as a VWAP Purchase-Type A or a VWAP Purchase-Type B), such
    VWAP Purchase Notice shall be void ab initio to the extent of the amount by which the VWAP Purchase Share Amount set forth in such VWAP Purchase Notice exceeds such applicable VWAP Purchase Maximum Amount, and the Investor shall have no
    obligation to purchase, and shall not purchase, and the Company shall have no obligation to issue, and shall not issue, such excess Shares pursuant to such VWAP Purchase Notice; provided, however, that the Investor shall remain
    obligated to purchase the applicable VWAP Purchase Maximum Amount pursuant to such VWAP Purchase. At or prior to 5:30 p.m., New York City time, on the Purchase Date for each VWAP Purchase, the Investor shall provide to the Company, by email
    correspondence to each of the individual notice recipients of the Company set forth in the applicable VWAP Purchase Notice, a written confirmation for such VWAP Purchase, setting forth the applicable VWAP Purchase Price per Share to be paid by the
    Investor for the Shares purchased by the Investor in such VWAP Purchase, and the total aggregate VWAP Purchase Price to be paid by the Investor for the total VWAP Purchase Share Amount purchased by the Investor in such VWAP Purchase. Notwithstanding

        VWAP Purchase-Type B”) and (b) whether a Limit Order Continue Election or a Limit Order Discontinue Election shall apply to such Intraday VWAP Purchase, on the applicable Purchase Date therefor, to purchase a specified Intraday VWAP
    Purchase Share Amount, which shall not exceed the applicable Intraday VWAP Purchase Maximum Amount, at the applicable Intraday VWAP Purchase Price therefor on such Purchase Date in accordance with this Agreement. The Company may deliver to the Investor

    VWAP Purchase to be effected pursuant to such Intraday VWAP Purchase Notice is specified by the Company as an Intraday VWAP Purchase-Type A or an Intraday VWAP Purchase-Type B), such Intraday VWAP Purchase Notice shall be void ab initio to the

    purchase, and the Company shall have no obligation to issue, and shall not issue, such excess Shares pursuant to such Intraday VWAP Purchase Notice; provided, however, that the Investor shall remain obligated to purchase the applicable
    Intraday VWAP Purchase Maximum Amount pursuant to such Intraday VWAP Purchase. At or prior to 5:30 p.m., New York City time, on the Purchase Date on which one or more Intraday VWAP Purchases shall have occurred, the Investor shall provide to the
    Company, by email correspondence to each of the individual notice recipients of the Company set forth in the applicable Intraday VWAP Purchase Notice, a written confirmation for each such Intraday VWAP Purchase, setting forth the applicable Intraday
    VWAP Purchase Price per Share to be paid by the Investor for the Shares purchased by the Investor in such Intraday VWAP Purchase, and the total aggregate Intraday VWAP Purchase Price to be paid by the Investor for the total Intraday VWAP Purchase Share
    Amount purchased by the Investor in such Intraday VWAP Purchase. Notwithstanding the foregoing, the Company shall not deliver any Intraday VWAP Purchase Notices to the Investor during the PEA Period or any Allowable Grace Period.

    each such Intraday VWAP Purchase (as applicable) (the “Purchase Share Delivery Date”). For (a) each VWAP Purchase, the Investor shall pay to the Company an amount in cash equal to the product of (1) the total number of Shares purchased by
    the Investor in such VWAP Purchase and (2) the applicable VWAP Purchase Price for such Shares, as full payment for such Shares purchased by the Investor in such VWAP Purchase, and (b) each Intraday VWAP Purchase, the Investor shall pay to the Company
    an amount in cash equal to the product of (1) the total number of Shares purchased by the Investor in such Intraday VWAP Purchase and (2) the applicable Intraday VWAP Purchase Price for such Shares, as full payment for such Shares purchased by the
    Investor in such Intraday VWAP Purchase, in each case via wire transfer of immediately available funds, not later than 5:00 p.m., New York City time, on the Trading Day immediately following the applicable Purchase Share Delivery Date for such VWAP
    Purchase and for each such Intraday VWAP Purchase (as applicable), provided the Investor shall have timely received, as DWAC Shares, all of such Shares purchased by the Investor in such VWAP Purchase and Intraday VWAP Purchase (as applicable) on such
    Purchase Share Delivery Date in accordance with the first sentence of this Section 3.3, or, if any of such Shares are received by the Investor after 1:00 p.m., New York City time, then the Company’s receipt of such funds in its designated account may
    occur on the Trading Day next following the Trading Day on which the Investor shall have received all of such Shares as DWAC Shares, but not later than 5:00 p.m., New York City time, on such next Trading Day. If the Company or its Transfer Agent shall
    fail for any reason to deliver to the Investor, as DWAC Shares in accordance with the first sentence of this Section 3.3, any Shares purchased by the Investor in a VWAP Purchase or an Intraday VWAP Purchase prior to 1:00 p.m., New York City time, on
    the Trading Day immediately following the applicable Purchase Share Delivery Date for such VWAP Purchase and for each such Intraday VWAP Purchase (as applicable) (other than a failure of the Investor or its Broker-Dealer to set up a DWAC and required
    instructions), and if on or after such Trading Day the Investor purchases (in an open market transaction or otherwise) Ordinary Shares to deliver in satisfaction of a sale by the Investor of such Shares that the Investor anticipated receiving from the
    Company on such Purchase Share Delivery Date in respect of such VWAP Purchase or such Intraday VWAP Purchase (as applicable) then, provided that the Investor has used its commercially reasonable efforts to purchase such Ordinary Shares only in
    normal brokerage transactions at a fair prevailing price per Ordinary Share then available, the Company shall, within one (1) Trading Day after the Investor’s request and subject to and conditioned upon the prior receipt by the Company of the
    Investor’s payment for the VWAP Purchase Price and Intraday VWAP Purchase Price (as applicable) in full, either (i) pay cash to the Investor in an amount equal to the Investor’s total purchase price (including brokerage commissions, if any) for the
    Ordinary Shares so purchased (the “Cover Price”) at which point the Company’s obligation to deliver such Shares as DWAC Shares shall terminate, or (ii) promptly honor its obligation to deliver to the Investor such Shares as DWAC Shares in
    accordance with the first sentence of this Section 3.3 and pay cash to the Investor in an amount equal to the excess (if any) of the Cover Price over the total purchase price over the total purchase price paid by the Investor pursuant to this Agreement
    for all of the Shares purchased by the Investor for such VWAP Purchase or Intraday VWAP Purchase (as applicable). If any issuance would result in the issuance of a fraction of an Ordinary Share, the Company shall round such fraction of an Ordinary
    Share up or down to the nearest whole share. All payments to be made by the Investor pursuant to this Agreement shall be made by wire transfer of immediately available funds to such account as the Company may from time to time designate by written
    notice to the Investor in accordance with the provisions of this Agreement.

  Section 3.4.      Compliance with Rules of Trading
      Market; Regulatory Approvals

   

  (a)       Exemption From Nasdaq Listing Rule 5635(d).
    The Company represents and warrants, as of the date hereof, that it has made all disclosures required under Nasdaq Listing Rule 5615(a)(3) such that the shareholder approval requirements and share issuance limitations under Nasdaq Listing Rule 5635(d)
    shall not be applicable for any purposes of this Agreement and the other Transaction Documents and the transactions contemplated hereby and thereby, including, without limitation, the issuance by the Company of the Commitment Shares to the Investor in
    accordance with Section 10.1(ii) of this Agreement and the issuance, sale and delivery of up to the Total Commitment of Shares in VWAP Purchases and Intraday VWAP Purchases (as applicable) that may be effected by the Company during the Investment
    Period pursuant to this Agreement.

   

  (b)       Regulatory Approval. Notwithstanding
    anything to the contrary contained in this Agreement, the Investor shall not be required to purchase or acquire any Ordinary Shares under this Agreement which, when aggregated with all other Ordinary Shares then beneficially owned by the Investor and
    its Affiliates, would exceed a regulatory threshold which would trigger an approval being required from a Governmental Authority (including, without limitation, the Foreign Acquisitions and Takeovers Act 1975 (Cth)) (a “Regulatory
        Approval”).

   

  (c)       General. The Company shall not issue or
    sell any Ordinary Shares pursuant to this Agreement if such issuance or sale would reasonably be expected to result in (a) a violation of the Securities Act or (b) a breach of the rules of the Trading Market.

   

  Section 3.5.      Beneficial Ownership Limitation.
    Notwithstanding anything to the contrary contained in this Agreement, the Investor shall not be required to purchase or acquire any Ordinary Shares under this Agreement which, when aggregated with all other Ordinary Shares then beneficially owned by
    the Investor (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder), would result in the beneficial ownership by the Investor of more than 4.99% of the outstanding Ordinary Shares (the “Beneficial
        Ownership Limitation”). Upon the written or oral request of the Investor, the Company shall promptly (but not later than the next business day on which the Company’s Transfer Agent is open for business) confirm orally or in writing to the
    Investor the number of Ordinary Shares then outstanding. The Investor and the Company shall each cooperate in good faith in the determinations required under this Section 3.5 and the application of this Section 3.5. The Investor’s written certification
    to the Company of the applicability of the Beneficial Ownership Limitation, and the resulting effect thereof hereunder at any time, shall be conclusive with respect to the applicability thereof and such result absent manifest error. The provisions of
    this Section 3.5 shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3.5 to the extent necessary to properly give effect to the limitations contained in this Section 3.5.

  Article IV

    REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE INVESTOR

   

  The Investor hereby makes the following representations, warranties and covenants to the Company as of each of (i) the date hereof, (ii) the
    Commencement Date and (iii) each Purchase Date (if any):

   

  Section 4.1.      Organization and Standing of the
        Investor. The Investor is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware.

   

  Section 4.2.     Authorization and Power. The
    Investor has the requisite limited liability company power and authority to enter into and perform its obligations under this Agreement and the Registration Rights Agreement and to purchase or acquire the Securities in accordance with the terms hereof.
    The execution, delivery and performance by the Investor of this Agreement and the Registration Rights Agreement and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary limited liability
    company action, and no further consent or authorization of the Investor or its officers is required. Each of this Agreement and the Registration Rights Agreement has been duly executed and delivered by the Investor and constitutes a valid and binding
    obligation of the Investor enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership, or similar laws
    relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable principles of general application (including any limitation of equitable remedies).

   

  Section 4.3.     No Conflicts. The execution,
    delivery and performance by the Investor of this Agreement and the Registration Rights Agreement and the consummation by the Investor of the transactions contemplated hereby and thereby do not and shall not (i) result in a violation of such Investor’s
    certificate of formation, limited liability company agreement or other applicable organizational instruments, (ii) conflict with, constitute a default (or an event which, with notice or lapse of time or both, would become a default) under, or give rise
    to any rights of termination, amendment, acceleration or cancellation of, any material agreement, mortgage, deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which the Investor is a party or is bound, (iii)
    create or impose any lien, charge or encumbrance on any property of the Investor under any agreement or any commitment to which the Investor is party or under which the Investor is bound or under which any of its properties or assets are bound, or (iv)
    result in a violation of any federal, state, local or foreign statute, rule, or regulation, or any order, judgment or decree of any Governmental Authority applicable to the Investor or by which any of its properties or assets are bound or affected,
    except, in the case of clauses (ii), (iii) and (iv), for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, prohibit or otherwise interfere with, in any
    material respect, the ability of the Investor to enter into and perform its obligations under this Agreement and the Registration Rights Agreement. The Investor is not required under any applicable federal, state or local law, rule or regulation to
    obtain any consent, authorization or order of, or make any filing or registration with, any Governmental Authority in order for it to execute, deliver or perform any of its obligations under this Agreement and the Registration Rights Agreement or to
    purchase or acquire the Securities in accordance with the terms hereof; provided, however, that for purposes of the representation made in this sentence, the Investor is assuming and relying in part upon the accuracy of the relevant
    representations and warranties and the compliance with the relevant covenants and agreements of the Company in the Transaction Documents to which it is a party.

  Certain confidential information contained in this document, marked by [***], has been omitted because Iris Energy Limited (the “Company”) has determined that the
      information (i) is not material and (ii) contains personal information.

   

  Section 4.4.     Investment Purpose. The Investor
    is acquiring the Securities for its own account, for investment purposes and not with a view towards, or for resale in connection with, the public sale or distribution thereof, in violation of the Securities Act or any applicable state securities laws;
    provided, however, that by making the representations herein, the Investor does not agree, or make any representation or warranty, to hold any of the Securities for any minimum or other specific term and reserves the right to dispose of
    the Securities at any time in accordance with, or pursuant to, a registration statement filed pursuant to the Registration Rights Agreement or an applicable exemption under the Securities Act. The Investor does not presently have any agreement or
    understanding, directly or indirectly, with any Person to sell or distribute any of the Securities. The Investor is acquiring the Securities hereunder in the ordinary course of its business.

   

  Section 4.5.      Accredited Investor Status. The
    Investor is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.

   

  Section 4.6.     Reliance on Exemptions. The
    Investor understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of U.S. federal and state securities laws and that the Company is relying in part upon the truth and
    accuracy of, and the Investor’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Investor set forth herein in order to determine the availability of such exemptions and the eligibility of the
    Investor to acquire the Securities.

   

  Section 4.7.     Information. All materials
    relating to the business, financial condition, management and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Investor have been furnished or otherwise made available to the
    Investor or its advisors, including the Commission Documents. The Investor understands that its investment in the Securities involves a high degree of risk. The Investor is able to bear the economic risk of an investment in the Securities and has such
    knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of a proposed investment in the Securities. The Investor and its advisors have been afforded the opportunity to ask questions of and
    receive answers from representatives of the Company concerning the financial condition and business of the Company and other matters relating to an investment in the Securities. Neither such inquiries nor any other due diligence investigations
    conducted by the Investor or its advisors, if any, or its representatives shall modify, amend or affect the Investor’s right to rely on the Company’s representations and warranties contained in this Agreement or in any other Transaction Document to
    which the Company is a party or the Investor’s right to rely on any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby (including the opinions of the
    Company’s counsel delivered pursuant to Section 7.2(xiv)). The Investor has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. The
    Investor understands that it (and not the Company) shall be responsible for its own tax liabilities that may arise as a result of this investment or the transactions contemplated by this Agreement.

      information (i) is not material and (ii) contains personal information.

   

  Section 4.8.     No Governmental Review. The
    Investor understands that no United States federal or state agency or any other government or Governmental Authority has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of an investment in the
    Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

   

  Section 4.9.      No General Solicitation. The
    Investor is not purchasing or acquiring the Securities as a result of any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities.

   

  Section 4.10.   Not an Affiliate. The Investor is
    not an officer, director or an Affiliate of the Company. As of the date of this Agreement, the Investor and its Affiliates do not beneficially own any Ordinary Shares or securities exercisable for or convertible into Ordinary Shares. During the
    Investment Period, the Investor will not acquire for its own account any Ordinary Shares or securities exercisable for or convertible into Ordinary Shares, other than pursuant to this Agreement; provided, however, that nothing in this
    Agreement shall prohibit or be deemed to prohibit the Investor from purchasing, in an open market transaction or otherwise, Ordinary Shares necessary to make delivery by the Investor in satisfaction of a sale by the Investor of Shares that the Investor
    anticipated receiving from the Company in connection with the settlement of a VWAP Purchase or an Intraday VWAP Purchase (as applicable) if the Company or its Transfer Agent shall have failed for any reason (other than a failure of the Investor or its
    Broker-Dealer to set up a DWAC and required instructions) to electronically transfer all of the Shares subject to such VWAP Purchase or such Intraday VWAP Purchase (as applicable) to the Investor on the applicable Purchase Share Delivery Date by
    crediting the Investor’s or its designated Broker-Dealer’s account at DTC through its DWAC delivery system in compliance with Section 3.3 of this Agreement. For the avoidance of doubt, the foregoing restriction does not apply to any Affiliate of the
    Investor, provided that any such purchases do not cause the Investor to violate any applicable Exchange Act requirement, including Regulation M.

   

  Section 4.11.   No Prior Short Sales. At no
    time prior to the date of this Agreement has the Investor, its sole member, any of their respective officers or any entity managed or controlled by the Investor or its sole member engaged in or effected, in any manner whatsoever, directly or
    indirectly, for its own account or for the account of any of its Affiliates, any (i) “short sale” (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of the Ordinary Shares or (ii) hedging transaction, which establishes a net
    short position with respect to the Ordinary Shares that remains in effect as of the date of this Agreement.

   

  Section 4.12.    Statutory Underwriter Status.. The Investor acknowledges that it will be disclosed as an “underwriter” and a
    “selling shareholder” in each Registration Statement and in any Prospectus contained therein to the extent required by applicable law and to the extent the Prospectus is related to the resale of Registrable Securities.

   

  Section 4.13.    Resales of Securities. The
    Investor will resell Securities purchased or acquired by the Investor from the Company pursuant to this Agreement only pursuant to the Registration Statement in which the resale of such Securities is registered under the Securities Act and the
    Prospectus contained therein, in a manner described under the caption “Plan of Distribution (Conflict of Interest)” in such Registration Statement and Prospectus, and in a manner in compliance with all applicable U.S. federal and applicable state
    securities laws, rules and regulations, including without limitation, any applicable prospectus delivery requirements of the Securities Act and otherwise in accordance with the terms and conditions of the Registration Rights Agreement.

    aggregate, have a material adverse effect on the business, properties, management, financial position, shareholders’ equity, results of operations or prospects of the Company and its Subsidiaries taken as a whole or on the performance by the Company of
    its obligations under the Transaction Documents (a “Material Adverse Effect”).

    of the other party, during the Investment Period (and for any period following the termination of this Agreement prior to such termination becoming effective as and to the extent specified in Section 8.3 solely pursuant to and in accordance with
    Section 8.3):

   

  Section 6.1.      Securities Compliance. The
    Company shall notify the Commission and the Trading Market, if and as applicable, in accordance with their respective rules and regulations, of the transactions contemplated by the Transaction Documents, and shall take all necessary action, undertake
    all proceedings and obtain all registrations, permits, consents and approvals for the legal and valid issuance of the Shares to the Investor in accordance with the terms of the Transaction Documents, as applicable.

   

  Section 6.2.     Issuance of Ordinary Shares. The
    Company will approve (by way of board resolution) and undertake the issuance of the requisite aggregate number of Ordinary Shares to enable the Company to timely effect (i) the issuance and delivery of all Commitment Shares to be issued and delivered
    to the Investor under Section 10.1(ii) hereof within the time period specified in Section 10.1(ii) hereof and (ii) the issuance, sale and delivery of all Shares to be issued, sold and delivered in respect of each VWAP Purchase effected under this

  Section 6.3.     Registration and Listing. The
    Company shall use its commercially reasonable efforts to cause the Ordinary Shares to continue to be registered as a class of securities under Section 12(b) of the Exchange Act, and to comply with its reporting and filing obligations under the Exchange

    could be reasonably expected to result in the delisting or suspension of the Ordinary Shares on the Trading Market (or other Eligible Market, as applicable). If the Company receives any final and non-appealable notice that the listing or quotation of
    the Ordinary Shares on the Trading Market (or other Eligible Market, as applicable) shall be terminated on a date certain, the Company shall promptly notify the Investor of such fact in writing and shall use its commercially reasonable efforts to cause

    that after the Closing Date, the Investor’s continued due diligence shall not be a condition precedent to the Commencement or to the Investor’s obligation to accept each VWAP Purchase Notice and each Intraday VWAP Purchase Notice timely delivered by

    Shares that the Investor is unconditionally obligated to purchase under any pending VWAP Purchase Notice or any pending Intraday VWAP Purchase Notice (as applicable), but has not yet received from the Company or its Transfer Agent pursuant to this
    Agreement, so long as (X) the Investor (or its Broker-Dealer, as applicable) delivers the Shares purchased pursuant to such pending VWAP Purchase Notice and the Shares purchased pursuant to such pending Intraday VWAP Purchase Notice (as applicable) to
    the purchaser thereof or the applicable Broker-Dealer promptly upon the Investor’s receipt of such Shares from the Company in accordance with Section 3.3 of this Agreement and (Y) neither the Company nor its Transfer Agent shall have failed for any

    lapses for any reason (including the issuance of a stop order by the Commission) or such Registration Statement or any post-effective amendment thereto, the Prospectus contained therein or any Prospectus Supplement thereto otherwise becomes unavailable
    to the Investor for the resale of all of the Registrable Securities included therein in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of forty-five (45) consecutive Trading Days
    or for more than an aggregate of ninety (90) Trading Days in any 365-day period, other than due to acts of the Investor; (d) trading in the Ordinary Shares on the Trading Market (or if the Ordinary Shares are then listed on an Eligible Market, trading
    in the Ordinary Shares on such Eligible Market) shall have been suspended and such suspension continues for a period of three (3) consecutive Trading Days; or (e) the Company is in material breach or default of any of its covenants and agreements
    contained in this Agreement, and, if such breach or default is capable of being cured, such breach or default is not cured within ten (10) Trading Days after notice of such breach or default is delivered to the Company pursuant to Section 10.4. Unless
    notification thereof is required elsewhere in this Agreement (in which case such notification shall be provided in accordance with such other provision), the Company shall promptly (but in no event later than twenty-four (24) hours) notify the Investor
    (and, if required under applicable law, including Regulation FD promulgated by the Commission, or under the applicable rules and regulations of the Trading Market (or Eligible Market, as applicable), the Company shall publicly disclose such information
    in accordance with Regulation FD and the applicable rules and regulations of the Trading Market (or Eligible Market, as applicable)) upon becoming aware of any of the events set forth in the immediately preceding sentence.

   

  Section 8.3.      Effect of Termination. In the
    event of termination by the Company or the Investor (other than by mutual termination) pursuant to Section 8.2, written notice thereof shall forthwith be given to the other party as provided in Section 10.5 and the transactions contemplated by this
    Agreement shall be terminated without further action by either party. Notwithstanding anything in this Agreement to the contrary, no termination of this Agreement by any party shall (i) become effective prior to the fifth (5th) Trading Day immediately following the settlement date related to any pending VWAP Purchase or any pending Intraday VWAP Purchase (as applicable) that has not been fully settled in accordance
    with the terms and conditions of this Agreement (it being hereby acknowledged and agreed that no termination of this Agreement shall limit, alter, modify, change or otherwise affect any of the Company’s or the Investor’s rights or obligations under the
    Transaction Documents with respect to any pending VWAP Purchase and any pending Intraday VWAP Purchase (as applicable), and that the parties shall fully perform their respective obligations with respect to any such pending VWAP Purchase and any pending
    Intraday VWAP Purchase under the Transaction Documents), or (ii) limit, alter, modify, change or otherwise affect the Company’s or the Investor’s rights or obligations under the Registration Rights Agreement, all of which shall survive any such
    termination solely as and to the extent provided therein. Nothing in this Section 8.3 shall be deemed to release the Company or the Investor from any liability for any breach or default under this Agreement, the Registration Rights Agreement or any of
    the other Transaction Documents to which it is a party, or to impair the rights of the Company and the Investor to compel specific performance by the other party of its obligations under the Agreement, the Registration Rights Agreement or any of the
    other Transaction Documents to which it is a party, in each case to the extent such breach or default shall have occurred prior to the effectiveness of any termination of this Agreement.

  Article IX

    INDEMNIFICATION

   

  Section 9.1.      Indemnification of Investor. In
    consideration of the Investor’s execution and delivery of this Agreement and acquiring the Shares hereunder and in addition to all of the Company’s other obligations under the Transaction Documents to which it is a party, subject to the provisions of
    this Section 9.1, the Company shall indemnify and hold harmless the Investor, its Affiliates, each of their respective directors, officers, shareholders, members, partners, employees, representatives, agents and advisors (and any other Persons with a
    functionally equivalent role of a Person holding such titles notwithstanding the lack of such title or any other title), each Person, if any, who controls the Investor (within the meaning of Section 15 of the Securities Act or Section 20(a) of the
    Exchange Act), and the respective directors, officers, shareholders, members, partners, employees, representatives, agents and advisors (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding the lack
    of such title or any other title) of such controlling Persons (each, an “Investor Party”), each of which shall be an express third party beneficiary of this Article IX, from and against all losses, liabilities, obligations, claims,
    contingencies, damages, costs and expenses (including all judgments, amounts paid in settlement, court costs, reasonable attorneys’ fees and reasonable costs of defense and investigation) (collectively, “Damages”) that any Investor Party
    may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement, the Registration Rights Agreement or in the other Transaction Documents to which
    it is a party or (b) any action, suit, claim or proceeding (including for these purposes a derivative action brought on behalf of the Company) instituted against such Investor Party arising out of or resulting from the execution, delivery, performance
    or enforcement of the Transaction Documents, other than, in the case of both clause (a) and (b), claims for indemnification within the scope of Section 6 of the Registration Rights Agreement; provided, however, that (x) the foregoing
    indemnity shall not apply to any Damages to the extent, but only to the extent, that such Damages resulted directly and primarily from a breach of any of the Investor’s representations, warranties, covenants or agreements contained in this Agreement or
    the Registration Rights Agreement, (y) in no event shall the Company be responsible for any special, indirect or consequential damages incurred by the Investor or any Investor Party, and (z) the Company shall not be liable under subsection (b) of this
    Section 9.1 to the extent, but only to the extent, that a court of competent jurisdiction shall have determined by a final judgment (from which no further appeals are available) that such Damages resulted directly and primarily from any acts or
    failures to act, undertaken or omitted to be taken by such Investor Party through its fraud, bad faith, gross negligence, or willful or reckless misconduct.

  Certain confidential information contained in this document, marked by [***], has been omitted because Iris Energy Limited (the “Company”) has determined that the information (i) is not
      material and (ii) contains personal information.

   

  The Company shall reimburse any Investor Party promptly upon demand (with
      accompanying presentation of sufficiently detailed documentary evidence) for all reasonable, documented out-of-pocket legal and other reasonable costs and expenses reasonably incurred by such Investor Party in connection with (i) any action, suit,
      claim or proceeding, whether at law or in equity, to enforce compliance by the Company with any provision of the Transaction Documents or (ii) any other any action, suit, claim or proceeding, whether at law or in equity, with respect to which it is
      entitled to indemnification under this Section 9.1; provided that the Investor shall promptly reimburse the Company for all such reasonable, documented out-of-pocket legal and other costs and expenses to the extent a court of competent
      jurisdiction determines that any Investor Party was not entitled to such reimbursement.

   

  An Investor Party’s right to indemnification or other remedies based upon
      the representations, warranties, covenants and agreements of the Company set forth in this Agreement shall not in any way be affected by any investigation or knowledge of such Investor Party. Such representations, warranties, covenants and agreements
      shall not be affected or deemed waived by reason of the fact that an Investor Party knew or should have known that any representation or warranty might be inaccurate or that the Company failed to comply with any agreement or covenant. Any
      investigation by such Investor or Investor Party shall be for its own protection only and shall not affect or impair any right or remedy hereunder.

   

  To the extent that the foregoing undertakings by the Company set forth in
      this Section 9.1 may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Damages which is permissible under applicable law, provided that in no event shall the
      Investor be obligated to contribute any amount in excess of the fees it actually receives pursuant to this Agreement.

   

  Section 9.2.     Indemnification Procedures. Promptly after
      an Investor Party receives notice of a claim or the commencement of an action for which the Investor Party intends to seek indemnification under Section 9.1, the Investor Party will notify the Company in writing of the claim or commencement of the
      action, suit or proceeding; provided, however, that failure to notify the Company will not relieve the Company from liability under Section 9.1, except to the extent it has been materially prejudiced by the failure to give notice. The Company will be
      entitled to participate in the defense of any claim, action, suit or proceeding as to which indemnification is being sought, and if the Company acknowledges in writing the obligation to indemnify the Investor Party against whom the claim or action is
      brought, the Company may (but will not be required to) assume the defense against the claim, action, suit or proceeding with counsel satisfactory to it. After the Company notifies the Investor Party that the Company wishes to assume the defense of a
      claim, action, suit or proceeding, the Company will not be liable for any further legal or other expenses incurred by the Investor Party in connection with the defense against the claim, action, suit or proceeding except that if, in the opinion of
      counsel to the Investor Party, it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and such Investor Party. In such event, the Company will pay the reasonable fees and
      expenses of no more than one separate counsel for all such Investor Parties promptly as such fees and expenses are incurred. Each Investor Party, as a condition to receiving indemnification as provided in Section 9.1, will cooperate in all reasonable
      respects with the Company in the defense of any action or claim as to which indemnification is sought. The Company will not be liable for any settlement of any action effected without its prior written consent, which consent shall not be unreasonably
      withheld, delayed or conditioned. The Company will not, without the prior written consent of the Investor Party, such consent not to be unreasonably withheld, delayed or conditioned, effect any settlement of a pending or threatened action with
      respect to which an Investor Party is, or is informed that it may be, made a party and for which it would be entitled to indemnification, unless the settlement includes an unconditional release of the Investor Party from all liability and claims
      which are the subject matter of the pending or threatened action.The remedies provided for in this Article IX are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Investor Party at law or in equity.

  Article X

      MISCELLANEOUS

   

  Section 10.1.   Certain Fees and Expenses; Commencement Irrevocable
          Transfer Agent Instructions.

   

  

  (i)          Certain Fees and Expenses. Each party shall bear
      its own fees and expenses related to the transactions contemplated by this Agreement; provided, however, that the Company, on or prior to the Closing Date, has paid to the Investor, by wire transfer of immediately available funds to
      an account designated by the Investor prior to the date of this Agreement, a non-accountable document preparation fee of $125,000 (the “Document Preparation Fee”), in connection with the preparation, negotiation, execution and delivery
      of the Transaction Documents and legal due diligence of the Company. The Company shall pay the Investor $7,500 per quarter in connection with the Investor’s ongoing due diligence and review of deliverables, subject to Section 6.13, except to the
      extent the applicable Representation Date has been waived or the Investor’s outside legal counsel otherwise shall not have delivered a negative assurance letter pursuant to Section 6.13 in such calendar quarter. The Company shall pay all U.S.
      federal, state and local stamp and other similar transfer and other taxes (other than income taxes) and duties levied in connection with issuance of the Securities pursuant hereto. The parties acknowledge that the Document Preparation Fee and the
      fees payable in connection with the Investor’s ongoing due diligence and review of deliverables are a reasonable estimate of, and are not disproportionate to, the probable costs of preparing the Transaction Documents and are less than or equal to the
      probable transaction costs of organizing a debt facility or capital raising in the amount of the Total Commitment.

   

  (ii)          Commitment Shares. In consideration for the
      Investor’s commitment pursuant to this Agreement, the Company shall deliver irrevocable instructions to its Transfer Agent to issue to the Investor, not later than 4:00 p.m. (New York City time) on the Commencement Date, a number of Ordinary Shares
      equal to the number of Commitment Shares required to be issued to the Investor hereunder in accordance with this Section 10.1(ii). For the avoidance of doubt, all of the Commitment Shares shall be fully earned as of the Commencement Date upon
      satisfaction of all conditions precedent thereto, regardless of whether any VWAP Purchases or Intraday VWAP Purchases are effected by the Company or settled hereunder or any subsequent termination of this Agreement. Upon issuance pursuant to this
      Section 10.1(ii), the Commitment Shares shall constitute “restricted securities” as such term is defined in Rule 144(a)(3) under the Securities Act. However, the offer and sale of the Commitment Shares by the Company to the Investor in accordance
      with the terms and conditions of this Agreement is exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2); provided, however, that at the request of and with the express representations, warranties
      and agreements of the Investor (including the representations, warranties and covenants of Investor set forth in Sections 4.10 through 4.13 and set forth in the Registration Rights Agreement) and, subject to effectiveness of the Initial Registration
      Statement including the Commitment Shares, the Commitment Shares to be issued from and after Commencement to or for the benefit of the Investor pursuant to this Agreement shall be issued to the Investor or its designated Broker-Dealer only as DWAC
      Shares and will not bear legends noting restrictions as to resale of such securities under federal or state securities laws, nor will any such securities be subject to stop transfer instructions. The Commitment Shares shall constitute Registrable
      Securities and shall be included in the Initial Registration Statement and any post-effective amendment thereto, and the Prospectus included therein,, in each case only to the extent required and otherwise in accordance with this Agreement and the
      Registration Rights Agreement.

  (iii)         Irrevocable Transfer Agent Instructions; Opinion of
          Counsel. On the Effective Date of the Initial Registration Statement and prior to Commencement, the Company shall deliver or cause to be delivered to its Transfer Agent an opinion of outside Australian counsel relating to the valid
      issuance of the Shares. On or prior to each Purchase Share Delivery Date, the Company shall deliver or cause to be delivered to the Transfer Agent irrevocable instructions executed by the Company with respect to all Shares to be delivered to the
      Investor on such Purchase Share Delivery Date pursuant to the terms hereof. For the avoidance of doubt, all Shares to be issued in respect of any VWAP Purchase Notice delivered to the Investor pursuant to this Agreement shall be issued to the
      Investor in accordance with Section 3.3 by crediting the Investor’s account at DTC as DWAC Shares, and the Company shall not take any action or give instructions to any Transfer Agent of the Company otherwise.

   

  Section 10.2.      Consent to Jurisdiction, Waiver of Jury Trial. Each
      of the Company and the Investor (a) hereby irrevocably submits to the jurisdiction of the U.S. District Court and other courts of the United States sitting in the City and County of New York in the State of New York for the purposes of any suit,
      action or proceeding arising out of or relating to this Agreement, and (b) hereby waives, and agrees not to assert in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such court, that the suit,
      action or proceeding is brought in an inconvenient forum or that the venue of the suit, action or proceeding is improper. The Company irrevocably appoints Cogency Global Inc., located 122 E. 42nd Street, 18th Floor, New York, New York 10168, as its
      authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agrees that service of process upon such authorized agent, and written notice of such service to the Company by
      the person serving the same to the address provided in this Section 10.2, shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company hereby represents and warrants that such authorized
      agent has accepted such appointment and has agreed to act as such authorized agent for service of process. The Company further agrees to take any and all action as may be necessary to maintain such designation and appointment of such authorized agent
      in full force and effect for a period of six years from the date of this Agreement. The Investor consents to process being served in any such suit, action or proceeding by mailing a copy thereof to the Investor at the address in effect for notices to
      it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing in this Section 10.2 shall affect or limit any right to serve process in any other manner permitted by law.

      FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTY HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.2.

      the Company has or hereafter may acquire any immunity (sovereign or otherwise) from jurisdiction of any court of (i) Australia, or any political subdivision thereof, (ii) the United States or the State of New York, (iii) any jurisdiction in which it

      assets or this Agreement, the Company hereby irrevocably waives such immunity in respect of its obligations under this Agreement to the fullest extent permitted by applicable law.

  Section 10.9.      Construction. The parties agree that

      not be employed in the interpretation of the Transaction Documents. In addition, each and every reference to share prices (including the Threshold Price) and number of Ordinary Shares in any Transaction Document shall, in all cases, be subject to

  Section 10.18.   Acknowledgement Regarding Relationship with
          Investor and B. Riley Securities. The Company acknowledges and agrees that the Investor is acting solely in the capacity of an arm’s-length purchaser with respect to this Agreement and the transactions contemplated by the Transaction
      Documents, and B. Riley Securities is acting as a representative of the Investor in connection with the transactions contemplated by the Transaction Documents, and of no other party, including the Company. The Company further acknowledges that while
      the Investor will be deemed to be a statutory “underwriter” with respect to certain of the transactions contemplated by the Transaction Documents in accordance with interpretive positions of the Staff of the Commission, the Investor is a “trader”
      that is not required to register with the Commission as a broker-dealer under Section 15(a) of the Exchange Act. The Company further acknowledges that the Investor and its representatives are not acting as a financial advisor or fiduciary of the
      Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated by the Transaction Documents, and any advice given by the Investor or any of its representatives (including B. Riley Securities) or agents in
      connection therewith is merely incidental to the Investor’s acquisition of the Securities. The Company understands and acknowledges that employees of B. Riley Securities may discuss market color, VWAP Purchase Notice timing and parameter
      considerations and other related capital markets considerations with the Company in connection with the Transaction Documents and the transactions contemplated thereby, in all cases on behalf of the Investor. The Company further represents to the
      Investor that the Company’s decision to enter into the Transaction Documents to which it is a party has been based solely on the independent evaluation of the transactions contemplated thereby by the Company and its representatives. The Company
      acknowledges and agrees that the Investor has not made and does not make any representations or warranties with respect to the transactions contemplated by the Transaction Documents other than those specifically set forth in Article IV.

      material and (ii) contains personal information.

   

  Section 10.19.   Investor’s Affiliate Relationships.
      Affiliates of the Investor, including B. Riley Securities, engage in a wide range of activities for their own accounts and the accounts of customers, including corporate finance, mergers and acquisitions, merchant banking, equity and fixed income
      sales, trading and research, derivatives, foreign exchange, futures, asset management, custody, clearance and securities lending. In the course of their respective business, Affiliates of the Investor may, directly or indirectly, hold long or short
      positions, trade and otherwise conduct such activities in or with respect to debt or equity securities or bank debt of, or derivative products relating to, the Company. Any such position will be created, and maintained, independently of the position
      the Investor takes in the Company. In addition, Aa any given time Affiliates of the Investor, including B. Riley Securities, may have been or in the future may be engaged by one or more entities that may be competitors with, or otherwise adverse to,
      the Company in matters unrelated to the transactions contemplated by the Transaction Documents, and Affiliates of the Investor, including B. Riley Securities may have or may in the future provide investment banking or other services to the Company in
      matters unrelated to the transactions contemplated by the Transaction Documents. Activities of any of the Investor’s Affiliates performed on behalf of the Company may give rise to actual or apparent conflicts of interest given the Investor’s
      potentially competing interests with those of the Company. The Company expressly acknowledges the benefits it receives from the Investor’s participation in the transactions contemplated by the Transaction Documents, on the one hand, and the
      Investor’s Affiliates’ activities, if any, on behalf of the Company unrelated to the transactions contemplated by the Transaction Documents, on the other hand, and understands the conflict or potential conflict of interest that may arise in this
      regard, and has consulted with such independent advisors as it deems appropriate in order to understand and assess the risks associated with these potential conflicts of interest. Consistent with applicable legal and regulatory requirements,
      applicable Affiliates of the Investor have adopted policies and procedures to establish and maintain the independence of their research departments and personnel from their investment banking groups and the Investor. As a result, research analysts
      employed by Affiliates of the Investor may hold views, make statements or investment recommendations or publish research reports with respect to the Company or the transactions contemplated by the Transaction Documents that differ from the views of
      the Investor.
